In addition, the neurotransmitter can bind to any one of the nearby smooth muscle cells, a flexibility not found in the NMJ. The chemicals that influence smooth muscle cells: As you'll recall, there is only one neurotransmitter released at the neuromuscular junction-acetylcholine.
Skeletal muscle is under voluntary control. Nerve impulses that originate in the central nervous system cause muscles to contract. Both neurons and muscle tissue conduct electrical current by moving ions across cellular membranes. A motor neuron ends in a synapse with a muscle fiber. The neuron releases acetylcholine and transfers the action potential to the muscle tissue. The signal will travel through the tissue and trigger the contraction of individual sarcomeres. One synapse generally controls an entire muscle fiber. One motor neuron usually controls several adjacent muscle fibers.
