neurogenic contraction

physiology

Quick Summary

Neurogenic contraction is initiated by signals from the nervous system transmitted to muscles at the neuromuscular junction. An electrical impulse travels along a motor nerve cell's axon to this junction. Chemical transmission occurs via the release of acetylcholine from the nerve terminal into the synaptic cleft, which then binds to receptors on the muscle membrane, triggering contraction. This process is crucial for all body movements, from intrinsic functions like breathing to external actions involving skeletal muscles.12
