Greg Boyles Posted September 21, 2011 Posted September 21, 2011 does every skeletal muscle cell have its own neuron? what is the size of neurons in peripheral tissues compared to skeletal muscle cells? Each skeletal muscle has a nerve which consists of a bundle of axons from more than one neurone. The end of the axons branch out from dendrons to dendrites that infiltrate all the individual muscle fibres which they activate when an action potential travels down the nerve. I would assume that the multiple axons in the nerve give the muscle contraction and anologue character where the amount of force applied can be varied. I.E. If an action potential flows down all the axons in the nerve then muscle contraction is strong where is if it only flows down some of the axons then the muscle contraction is weaker. Something like that any way.
