MICROANATOMY

Detailed explanation-1: -The synapse is a specialized structure that allows one neuron to communicate with another neuron or a muscle cell.

Detailed explanation-2: -From here, the action potential is sent through an axon down to its ending branches, called axon terminals, to muscle fibers which they innervate. The place where an axon terminal meets the muscle fiber is the neuromuscular junction.

Detailed explanation-3: -The neuromuscular junction (NMJ) is a synaptic connection between the terminal end of a motor nerve and a muscle (skeletal/ smooth/ cardiac). It is the site for the transmission of action potential from nerve to the muscle.

Detailed explanation-4: -Acetylcholine receptors In vertebrates, the acetylcholine receptor subtype that is found at the neuromuscular junction of skeletal muscles is the nicotinic acetylcholine receptor (nAChR), which is a ligand-gated ion channel.

Detailed explanation-5: -The junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction.
