MUSCLE PHYSIOLOGY

Detailed explanation-1: -The release of acetylcholine occurs when an action potential is relayed and reaches the axon terminus in which depolarization causes voltage-gated calcium channels to open and conduct an influx of calcium, which will allow the vesicles containing acetylcholine for release into the synaptic cleft.

Detailed explanation-2: -Neurotransmitters are released from synaptic vesicles in presynaptic neurons in response to neural activity, diffuse across the synaptic cleft, and bind specific receptors in order to bring about changes in postsynaptic neurons.

Detailed explanation-3: -Key Term: Calcium Ions Calcium ions stimulate vesicles containing acetylcholine to move toward and fuse with the plasma membrane. Acetylcholine is then released into the synaptic cleft.

Detailed explanation-4: -Neurotransmitters are chemicals that are used to relay, amplify and modulate electrical signals between a neuron and another cell. They are released by vesicles present in the pre-synaptic knob of axon terminals.
