The area where muscle and nerve fibers intersect is called the neuromuscular junction. This junction is functions as the site of communication that connects the nervous and muscular system.
[Edit]
Well of course they meet at the neuromuscular junction
Neuromuscular junction (NMJ)
acetylcholine
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
What is a synapse between a nerve fiver and a muscle fiber
ganglionic synapse
Calcium ions
Dendrites
all-or-none law is the principle that the strength by which a nerve or muscle fiber responds to a stimulus is not dependent on the strength of the stimulus. If the stimulus is any strength above threshold, the nerve or muscle fiber will give a complete response or otherwise no response at all
The sarcolemma is the cell membrane of a muscle fiber. It surrounds and protects the muscle fiber and controls the movement of substances into and out of the cell. The sarcolemma plays a crucial role in muscle contraction and the transmission of nerve impulses to the muscle fiber.
A long nerve fiber that conveys electrical impulses to other cells is called an axon.
