WebOct 27, 2024 · The neuromuscular junction (NMJ) is the most important synapse. It’s the synapse between the nervous system and the skeletal muscle. More specifically, it’s the synapse between the axon of the alpha motor neuron in the anterior horn of the spinal cord and the skeletal muscle it innervates. Like all chemical synapses, there is a ... WebRelaxation begins when the release of acetylcholine ceases at the neuromuscular junction. The acetylcholine already in the synapse is broken down by acetylcholinesterase, ending action potential generation and propagation. This stops the release of Ca 2+ from the sarcoplasmic reticulum (SR).

WebAcetylcholine (ACh) is a small molecule neurotransmitter best known for its role at the. neuromuscular junction. , the synapse between a motor neuron and a muscle fiber. In the presynaptic terminal, acetylcholine is synthesized from acetyl coenzyme A (acetyl CoA) and choline via the enzyme choline acetyltransferase (ChAT). WebThe Effect of Acetylcholine on Muscle. Close-up man flexing his bicep. Acetylcholine is a chemical messenger, a neurotransmitter, released by nerve cells in many parts of the peripheral nervous system. It controls the contraction of all skeletal or voluntary muscles, for instance. It also affects the contraction of smooth and cardiac muscle.
