Skeletal System Quotes

I wasn’t sure my skeletal system had found a way of walking freely in the Societal System

There is simply no other exercise, and certainly no machine, that produces the level of central nervous system activity, improved balance and coordination, skeletal loading and bone density enhancement, muscular stimulation and growth, connective tissue stress and strength, psychological demand and toughness, and overall systemic conditioning than the correctly performed full squat.

The postures are only the "skin" of yoga. Hidden behind them are the "flesh and blood" of breath control and mental techniques that are still more difficult to learn, as well as moral practices that require a lifetime of consistent application and that correspond to the skeletal structure of the body. The higher practices of concentration, meditation and unitive ecstasy(samadhi) are analogous to the circulatory and nervous system." Georg Feuerstein The Deeper Dimension of Yoga

Some say we are not like humans but we are more like them than we are different. Man and animals are in the same species as mammals as they have mammary glands that produce the milk to nurse their young. Their lungs breathe air and their blood is warm. They are vertebrates in that their skeletal system and well-designed spines hold their bodies together. Each cell is made of molecules, each molecule is made of atoms, and each atom is made of protons, neutrons and mostly electrons, which are made of waves of fibered light.

Healthy posture is based on natural positions that balance and support your skeletal system’s curves and weight-bearing abilities against the force of gravity.

I don't want to read your walls ... I don't want to read your hang-ups. I don't want to read skeletal concepts of people who operate without the influence of a limbic system. You are not an archaeologist excavating and presenting old bones. Your work is the connective tissue. Give me some DNA, or don't bother.

What a skeletal wreck of man this is. Translucent flesh and feeble bones, the kind of temple where the whores and villains try to tempt the holistic domes. Running rampid with free thought to free form, and the free and clear. When the matters at hand are shelled out like lint at a laundry mat to sift and focus on the bigger, better, now. We all have a little sin that needs venting, virtues for the rending and laws and systems and stems are ripped from the branches of office, do you know where your post entails? Do you serve a purpose, or purposely serve? When in doubt inside your atavistic allure, the value of a summer spent, and a winter earned. For the rest of us, there is always Sunday. The day of the week the reeks of rest, but all we do is catch our breath, so we can wade naked in the bloody pool, and place our hand on the big, black book. To watch the knives zigzag between our aching fingers. A vacation is a countdown, T minus your life and counting, time to drag your tongue across the sugar cube, and hope you get a taste. WHAT THE FUCK IS ALL THIS FOR? WHAT THE HELL’S GOING ON? SHUT UP! I can go on and on but lets move on, shall we? Say, your me, and I’m you, and they all watch the things we do, and like a smack of spite they threw me down the stairs, haven’t felt like this in years. The great magnet of malicious magnanimous refuse, let me go, and punch me into the dead spout again. That’s where you go when there’s no one else around, it’s just you, and there was never anyone to begin with, now was there? Sanctimonious pretentious dastardly bastards with their thumb on the pulse, and a finger on the trigger. CLASSIFIED MY ASS! THAT’S A FUCKING SECRET, AND YOU KNOW IT! Government is another way to say better…than…you. It’s like ice but no pick, a murder charge that won’t stick, it’s like a whole other world where you can smell the food, but you can’t touch the silverware. Huh, what luck. Fascism you can vote for. Humph, isn’t that sweet? And we’re all gonna die some day, because that’s the American way, and I’ve drunk too much, and said too little, when your gaffer taped in the middle, say a prayer, say a face, get your self together and see what’s happening. SHUT UP! FUCK YOU! FUCK YOU! I’m sorry, I could go on and on but their times to move on so, remember: you’re a wreck, an accident. Forget the freak, your just nature. Keep the gun oiled, and the temple cleaned shit snort, and blaspheme, let the heads cool, and the engine run. Because in the end, everything we do, is just everything we’ve done.

Dagon left his office and made his way down to the infirmary. Adaos looked up when he entered. Eliana lay curled on her side, covered by a sheet. Though dark wavy tresses hid much of her face, she appeared to be sleeping deeply. “She still rests,” Adaos murmured. “Her injuries?” “All damage to her skeletal system has healed completely. Some of the damage to her musculature and skin has as well. The damage to her organs is still repairing.” “Did you give her a silna to accelerate her healing?” Even with the serum, it would take Segonian warriors longer to recuperate from such wounds. Adaos shook his head. “A silna wasn’t necessary. Her ability to repair and regenerate rivals that of the Sectas with their nanodocs.” “Amazing.” Dagon crouched next to the bed. Reaching out, he gently drew the hair back from Eliana’s face and tucked it behind her ear. “She’s too thin,” he whispered, noting the prominent cheekbones. Though the burns had healed, some of the cuts and bruising remained. “Did you provide her with sustenance before she fell asleep?” “Yes. I also fed her fluids and nutrition intravenously.” “She doesn’t like needles.” “She slept through it.” Eliana’s eyelashes fluttered. Her lids rose, revealing deep brown eyes bereft of the amber glow. She studied him a moment, then offered him a sleepy smile. One small hand burrowed out from under the covers and stretched toward him. Soft fingers came to rest on his cheek and stroked the stubble there. “Dagon.” Warmth unfurled in his chest at the tender touch. His pulse picked up its pace. “Eliana.

Needless to say, elderly people taking steroids may also experience the same side effects as younger persons. So, if you are a senior and need to be on a long course of steroids, what should you do? We would suggest a practical approach—which could apply to anyone on steroids, regardless of age, but may be particularly relevant for seniors because they are particularly vulnerable to side effects: • Understand and verify the need for steroids in your own situation, weighing the anticipated benefit with the possible risks. This means that you should explore the range of other treatments that may be available for your particular condition. You need to learn about the benefits and risks of any other treatment suggested. In other words, get all the information you can prior to going on treatment, be it with steroids or other medications. • Be sure that your health is well-assessed before or at the start of therapy. If you have underlying, separate health conditions, those should be noted and followed while you are on steroids. • Assess bodily systems that might particularly be affected by being on steroids. This means an assessment of your skeletal health, your eyes, your teeth, and your internal organs. • Request guidance about staying active. Physical therapy should be planned, to minimize the chances that your muscles and joints will be overtaxed or that any existing damage might get worse. • Ask to reassess the length and dose of your medication course at various intervals. A reasonable interval is every couple of months, if you are on a long course of steroids.

The stars of the Milky Way galaxy trace a big, flat circle. With a diameter-to-thickness ratio of one thousand to one, our galaxy is flatter than the flattest flapjacks ever made. In fact, its proportions are better represented by a crépe or a tortilla. No, the Milky Way’s disk is not a sphere, but it probably began as one. We can understand the flatness by assuming the galaxy was once a big, spherical, slowly rotating ball of collapsing gas. During the collapse, the ball spun faster and faster, just as spinning figure skaters do when they draw their arms inward to increase their rotation rate. The galaxy naturally flattened pole-to-pole while the increasing centrifugal forces in the middle prevented collapse at midplane. Yes, if the Pillsbury Doughboy were a figure skater, then fast spins would be a high-risk activity. Any stars that happened to be formed within the Milky Way cloud before the collapse maintained large, plunging orbits. The remaining gas, which easily sticks to itself, like a mid-air collision of two hot marshmallows, got pinned at the mid-plane and is responsible for all subsequent generations of stars, including the Sun. The current Milky Way, which is neither collapsing nor expanding, is a gravitationally mature system where one can think of the orbiting stars above and below the disk as the skeletal remains of the original spherical gas cloud. This general flattening of objects that rotate is why Earth’s pole-to-pole diameter is smaller than its diameter at the equator. Not by much: three-tenths of one percent—about twenty-six miles. But Earth is small, mostly solid, and doesn’t rotate all that fast. At twenty-four hours per day, Earth carries anything on its equator at a mere 1,000 miles per hour. Consider the jumbo, fast-rotating, gaseous planet Saturn. Completing a day in just ten and a half hours, its equator revolves at 22,000 miles per hour and its pole-to-pole dimension is a full ten percent flatter than its middle, a difference noticeable even through a small amateur telescope. Flattened spheres are more generally called oblate spheroids, while spheres that are elongated pole-to-pole are called prolate. In everyday life, hamburgers and hot dogs make excellent (although somewhat extreme) examples of each shape. I don’t know about you, but the planet Saturn pops into my mind with every bite of a hamburger I take.

system. At 12:04:03, every screen in the building strobed for eighteen seconds in a frequency that produced seizures in a susceptible segment of Sense/Net employees. Then something only vaguely like a human face filled the screens, its features stretched across asymmetrical expanses of bone like some obscene Mercator projection. Blue lips parted wetly as the twisted, elongated jaw moved. Something, perhaps a hand, a thing like a reddish clump of gnarled roots, fumbled toward the camera, blurred, and vanished. Subliminally rapid images of contamination: graphics of the building’s water supply system, gloved hands manipulating laboratory glassware, something tumbling down into darkness, a pale splash. . . . The audio track, its pitch adjusted to run at just less than twice the standard playback speed, was part of a month-old newscast detailing potential military uses of a substance known as HsG, a biochemical governing the human skeletal growth factor. Overdoses of HsG threw certain bone cells into overdrive, accelerating growth by factors as high as one thousand percent.

Baseball may be called the national pastime, but it survives on the sentimentality of middle-age men who wistfully dream of playing catch with their fathers and sons. Football, with its dull stoppages, lost its military-industrial relevance with the end of the Cold War, and has become as tired and predictable in performance as it is in political metaphor. The professional game floats on an ocean of gambling, the players' steroid-laced bodies having outgrown their muscular and skeletal carriages. Biceps rip from their moorings, ankles break on simple pivots. Achilles' tendons shrivel like slugs doused with salt. Soccer and basketball are the only mainstream sports that truly plug into the modem-pulse of a dot-com society. Soccer is perfectly suited for a country of the hamster-treadmill pace, the remote-control zap and the national attention deficit—two 45-minute halves, the clock never stops, no commercial interruptions, the final whistle blows in less than two hours. It is a fluid game of systemized chaos that, no matter how tightly scripted by coaches, cannot be regulated any more than information can be truly controlled on the Internet.

The pathways with axons pointed towards the periphery, and which conduct impulses outward, are called efferent pathways. Their origins can ultimately be traced to the motor cortex, next to the sensory cortex at the top of the brain. Their axons descend the spinal cord and fan out into the body, terminating in synapses with the striated skeletal and cardiac muscles, and the smooth muscles of the vessels, internal organs, and glands. They are alternately termed the motor pathways. Their role is to carry out to the body, from every level in the nervous system, all of the impulses which control the appropriate contraction and lengthening of the entire musculature. Their signals are translated into the various behavioral effects which the mind chooses in response to input.

Efferent impulses may be conducted along one of two major pathways of motor neurons as they pass from the brain through the cord and out to the muscles, and together these longitudinal pathways provide for the convergence of the influences from all levels of the central nervous system upon the motor units. The fastest of these descending routes is the direct corticospinal pathway. As the name suggests, the cell bodies of this path are in the cortex, and they send their long axons directly through the brain and down the spinal cord without any interruptions. These axons do not form any synapses until they reach their corresponding motor neurons in the cord, and thus they form direct connections between specific cells in the motor cortex and specific motor neurons at each level of the cord, making one-to-one relationships between cortical cells and peripheral motor units. This pathway bypasses most of the intermediate circuitry of the lower brain and the spinal cord. This gives it the advantage of speedy transmission. The axons which are bundled together within it maintain a constant spatial relationship throughout their length, faithfully reflecting the spatial relationships of the cell bodies in the cortex. The longest axons, reaching all the way to the end of the cord, lie the closest to the center of the cord, and the progressively shorter axons which synapse to motor neurons in progressively higher segments, are carefully laid down in layers progressively far from the center of the cord, so that a “map” of skeletal muscle relationships is projected onto the motor cortex. This gives a high degree of specificity to this direct corticospinal tract. This direct pathway is the mediator of fine, intricate movements, which require close conscious attention and constantly refined adjustment. When it is severed, actions become clumsier, because the sharp edge of delicate conscious control is missing.

We have, then, two separate motor systems within us. One of them, the alpha system, originates in the cortex, is closely associated with conscious sensations in the sensory cortex, operates the skeletal muscles, and is responsive to my conscious commands to lift an arm, take a step, and so on. The other system, the gamma, originates deep inside the older part of the brain, is associated with lower sensory centers that produce no conscious sensations, controls the lengths of my intrafusal fibers, and functions primarily beneath the levels of my conscious awareness. These two systems are linked together at their peripheries by the anulospiral receptor, which wraps the middle of the intrafusal fiber and synapses in the spinal column with its alpha partner. And because of these spinal reflex arcs, any impulse and movement initiated by one of the systems necessarily triggers an immediate reciprocal impulse and movement in the other, since the anulospiral receptor is stretched or compressed in either case.

The sensory roles of the anulospiral receptor and the tendon organ are absolutely central in this process of exerting and adjusting muscle tone. These devices establish the “feel” for length and tension, and it is this feeling which is maintained by the gamma motor system, the reflex arcs, and the alpha skeletal muscles. All of my muscle cells—both alpha and gamma—are continually felt by the mind as they work, whether most of these “feelings” ever reach my conscious awareness or not. And it is primarily these muscular feelings which supply my central nervous system with the constant information necessary to successfully combine the demands of free motion with those of basic structural stability. The sophistication required for this maintenance of structure and flexibility can be appreciated if we remember that almost any simple motion—such as raising the arm out to the side—changes either the length or the tension values in most of the body’s muscle cells. If one is to avoid tipping towards the extended arm, then the feet, the legs, the hips, the back, the neck, and the opposite arm all must participate in a new distribution of balance created by the “isolated” movement of raising the arm. The difficulties experienced by every child learning to sit, to stand erect, and to walk with an even gait attest to the complexity of the demands which these shifts in balance and tone make upon us. The entire musculature must learn to participate in the motion of any of its parts. And to do this, the entire musculature must feel its own activity, fully and in rich detail. Competent posture and movement are among the chief points of sensory self-awareness. The purpose of bodywork is to heighten and focus this awareness. It is the child’s task during this early motor training to experiment by trial and error, and to set the precise lengths and tensions—and changes in length and tension—in all his muscle fibers for these basic skills of standing and walking. This is the education of the basal ganglia and the gamma motor system, as learned reflex responses are added to our inherited ones. The lengths and rates of change of the spindle fibers are set at values which experience has confirmed to be appropriate for the movement desired, and then the sensorimotor reflex arcs of the spindles and the Golgis command the alpha motor nerves, and hence the skeletal muscles, to respond exactly to those specifications that have been established in the gamma system by previous trial and error. And this chain of events holds true not only for the actual limb being moved, but for all other parts of the musculature that must brace, or shift, or compensate in any way. In this complicated process, the child is guided primarily by sensory cues which become more consistent and more predictable with every repetition of his efforts.

Thus two different kinds of muscle contractions are possible, each using a different sort of patterning principle to control movements. The motor cortex and the alpha neurons directly cause contractions of the skeletal muscles, contractions which continue as long as the command signals are being sent. The brain stem and the gamma neurons, on the other hand, cause contractions that are mediated through the spindle system, and their commands cease once a predetermined length has been achieved, at which point the stretch reflex arrests further effort. The alpha system organizes its commands in terms of the duration of neural bursts; the gamma system organizes its commands in terms of the starting and stopping lengths of the muscle fibers. In other words, the stimulation patterns which organize the alpha contractions are coded as a function of time—the duration of the bursts coming from the motor cortex. And the patterns which organize the gamma contractions are coded as a function of space, stimulation ceasing when a predetermined length is achieved in the anulospiral gauges.

The evolution of hundreds of thousands of generations has established the necessary muscle lengths and tension loads in order to keep my joints together and to support my structure against the pull of gravity. This information appears to be stored in some form in the brainstem—particularly in the basal ganglia—and transferred genetically from one generation to the next. The whole gamma motor system of the individual then uses this information to adjust the lengths of his muscle spindles appropriately, which in turn adjust the lengths and tensions of his skeletal muscles throughout the reflex arcs.

Archeologists find ancient text messaging system: Rocks with text thrown to recipients - Skeletal remains show high level of head trauma.

Cardiac muscle tissue occurs only in the heart (the body’s blood pump), where it constitutes the bulk of the heart walls. Like skeletal muscle cells, cardiac muscle cells are striated (see Figure 4.9b, p. 139), but cardiac muscle is not voluntary. Indeed, it can and does contract without being stimulated by the nervous system. Most of us have no conscious control over how fast our heart beats.

A well-conditioned oarsman or oarswoman competing at the highest levels must be able to take in and consume as much as eight liters of oxygen per minute; an average male is capable of taking in roughly four to five liters at most. Pound for pound, Olympic oarsmen may take in and process as much oxygen as a thoroughbred racehorse. This extraordinary rate of oxygen intake is of only so much value, it should be noted. While 75–80 percent of the energy a rower produces in a two-thousand-meter race is aerobic energy fueled by oxygen, races always begin, and usually end, with hard sprints. These sprints require levels of energy production that far exceed the body’s capacity to produce aerobic energy, regardless of oxygen intake. Instead the body must immediately produce anaerobic energy. This, in turn, produces large quantities of lactic acid, and that acid rapidly builds up in the tissue of the muscles. The consequence is that the muscles often begin to scream in agony almost from the outset of a race and continue screaming until the very end. And it’s not only the muscles that scream. The skeletal system to which all those muscles are attached also undergoes tremendous strains and stresses. Without proper training and conditioning—and sometimes even with them—competitive rowers are apt to experience a wide variety of ills in the knees, hips, shoulders, elbows, ribs, neck, and above all the spine. These injuries and complaints range from blisters to severe tendonitis, bursitis, slipped vertebrae, rotator cuff dysfunction, and stress fractures, particularly fractures of the ribs. The common denominator in all these conditions—whether in the lungs, the muscles, or the bones—is overwhelming pain. And that is perhaps the first and most fundamental thing that all novice oarsmen must learn about competitive rowing in the upper echelons of the sport: that pain is part and parcel of the deal. It’s not a question of whether you will hurt, or of how much you will hurt; it’s a question of what you will do, and how well you will do it, while pain has her wanton way with you.

In 2015, scientists from the Center for Space Medicine and Extreme Environments in Berlin followed athletes competing in the Yukon Arctic Ultra. They wanted to know: How does the human body cope in such a brutal context? When the researchers analyzed the hormones in the bloodstreams of the athletes, one hormone, irisin, was wildly elevated. Irisin is best known for its role in metabolism—it helps the body burn fat as fuel. But irisin also has powerful effects on the brain. Irisin stimulates the brain’s reward system, and the hormone may be a natural antidepressant. Lower levels are associated with an increased risk of depression, and elevated levels can boost motivation and enhance learning. Injecting the protein directly into the brains of mice—not something scientists are ready to try with humans—reduces behaviors associated with depression, including learned helplessness and immobility in the face of threats. Higher blood levels of irisin are also associated with superior cognitive functioning, and may even prevent neurodegenerative diseases such as Alzheimer’s. The Yukon Arctic Ultra athletes entered the event with extraordinarily high blood levels of this hormone, far beyond levels seen in most humans. Over the course of the event, their irisin levels climbed higher. Even as their bodies fell victim to hypothermia and exhaustion, the athletes were bathing their brains in a chemical that preserves brain health and prevents depression. Why were their blood levels of irisin so elevated? The answer lies in both the nature of the event and what the athletes had to do to get there. Irisin has been dubbed the “exercise hormone,” and it is the best-known example of a myokine, a protein that is manufactured in your muscles and released into your bloodstream during physical activity. (Myo means muscle, and kine means “set into motion by.”) One of the greatest recent scientific breakthroughs in human biology is the realization that skeletal muscles act as an endocrine organ. Your muscles, like your adrenal and pituitary glands, secrete proteins that affect every system of your body. One of these proteins is irisin. Following a single treadmill workout, blood levels of irisin increase by 35 percent. The Yukon Arctic Ultra required up to fifteen hours a day of exercise. Muscle shivering—a form of muscle contraction—also triggers the release of irisin into the bloodstream. For the Yukon Arctic Ultra competitors, the combination of extreme environment and extreme exertion led to exceptionally high levels of this myokine.

Tissue Tissue is a group of cells in animals and plants that forms a definite kind of structural material with a specific function. Muscle Muscle is a tissue in the body, often attached to bones, that can tighten and relax to produce motion. Skeletal Muscle Skeletal muscle is muscle tissue connected to the skeleton to form part of the system that moves the limbs and other parts of the body.

Much like the skeletal and muscular systems in biological entities, robots employ joints and linkages to achieve motion.
