What are the 3 types of muscle contraction?

I answered that same question yesterday:\nThe impulse reaches the terminal end of the motor neuron and breaks open the synaptic vesicles, releasing the neurotransmitter acetylcholine into the synaptic cleft.\nACh then binds to receptor molecules in the motor end plate of the muscle fiber.\nThe action potential is started in sarcolemma and passes along the membrane until it reaches the sarcoplasmic reticulum releasing calcium. Calcium diffuses in sarcoplasm and binds to the troponin in the thin filaments.\nThe binding sites on the actin molecules are freed, allowing\nthe heads of myosin (thick filaments) to attach on the binding sites forming the cross-bridges connections.\nThe cross-bridges shift their angle causing the thin filaments to slide over the thick filaments; this produces the contraction.\nATP is needed for the last step. ATP is bound to myosin; calcium activates ATP breakdown into ADP and phosphate.\nPart of the energy produced is used to move bridges, the other part is released as heat, increasing the body temperature.\nMore ATP breaks the bond between thick and thin filaments in the cross bridge; calcium returns to thesarcoplasmic reticulum and the thin filaments return to their original position, closing off the binding site to cross bridges and causing the muscle to relaxe.

i would say cardiac muscles.

diff muscle types have diff shapes and characteristics\n1. Cardiac muscle - spindle shape, nuclei are centrally located, involuntary muscle, branching, primarily found in the heart\n\n2. Smooth muscle - spindle shape, involuntary, not branching, primarily found in the gastrointestinal tract\n\n3. Skeletal muscle - branching, voluntary, multi-nucleited, straited, found all over the body

Tens units don't cause muscle contraction, they are only good for pain because they are sensory only. You are wasting your time. And you're going to die anyway.

All of the above are well understood, it's just that skeletal and cardiac mucsle are more complicated, therefore there is more information on them.  Smooth muscle contraction can function solely on its intrinsic plexus, its built-in nervous system that only receives fine tuning from the para and sympathetic nervous systems.  It even has its own immune system, Peyer's Patches for example.

A muscle (or even a few fibers of a muscle) that involuntarily (without consciously willing it) contracts is called a "spasm." If the spasm is forceful and sustained, it becomes a cramp.\nA muscle cramp is thus defined as an involuntarily and forcibly contracted muscle that does not relax.

1. At the neuromuscular juncture, ACh released by the synaptic terminal binds to receptors on the sarcolemma.\n\n2. The resulting change in the transmembrane potential of the muscle fiber leads to the production of action petential that spreads across the entire surface of the muscle fiber and along the T tubules.\n\n3.The sarcoplasmic reticulum releases stored calcium ions, increasing the calcium concentration of the sarcoplasm in and around the sarcomeres.\n\n4. Calcium ions bind to triponin, producing a change in the orientation of the troponin-tropomyosin complex that exposes active sites on the thin filaments (actin). Cross-bridges form when myosin heads bind to the active sites on F actin.\n\n5. The contraction begins as repeated cycles of cross-bridge binding, pivoting, and detatchment occur, powered by the hydrolysis of ATP. These events produce filament sliding, and the muscle fiber shortens.

The sets of muscles that have the finest control have the fewest muscle fibers per motor unit.  This makes sense because when a neuron depolarizes all of the muscle fibers it is connected to depolarize and contract.  This is refered to as a "All-or-None" response.  Muscle fibers don't contract half way.  So if you want precise control over your muscles you have to have a lot of neurons innervating it.

They are considered to be contractions.

1. respiratory system, lung - there will be more frequent relaxation and contraction that may be a burden to the lung\n\n2. muscular/muscles, there will be a lactic acid production as a result of strenuous muscular activity (shortage of O2)

If the 3 rolls aren't huge....exercise, exercise, exercise.  I have found that stretching exercises are the easiest and most effective with quick results.  Yoga exercises are great.   Make sure not to push too far though at the beginning.   Take hot salt (1/2 hr) bath soaks  after exercising and push through the stiffness the next couple of days to carry on.   Once the initial muscle stiffness is out of the way, the rest is a breeze.   Good luck.

Nerve impulse is connected with Na and K while muscle contraction has to do with Ca and Mg

1 biceps and triceps,biceps bends the arm and triceps strait it.\n2 flexors muscles and extensor muscles of the forearm,flexors bends the finguers and extensors straiten them.\n3 biceps femoris and cuadriceps,biceps femoris bens the leg and cuadriceps extend it.
