MUSCLE PHYSIOLOGY

Detailed explanation-1: -neurotransmitter release, discharge of chemical substances known as neurotransmitters from a neuron in response to a given stimulus. Neurotransmitter release occurs at synapses, which are the sites of transmission of electric nerve impulses between two neurons or between a neuron and a gland or muscle cell.

Detailed explanation-2: -Neurotransmitter release from presynaptic nerve terminals is a central component of synaptic transmission, the main process by which neurons communicate with each other and with target cells. Neurotransmitter is packaged inside small vesicles in the presynaptic nerve terminal.

Detailed explanation-3: -Acetylcholine (ACh) is a neurotransmitter released by motor neurons that binds to receptors in the motor end plate. Neurotransmitter release occurs when an action potential travels down the motor neuron’s axon, resulting in altered permeability of the synaptic terminal membrane and an influx of calcium.
