GENERAL HISTOLOGY

Detailed explanation-1: -This special form of synapse between a motor neuron axon and a muscle fibre is called a neuromuscular junction. The arrival of a nerve impulse at the neuromuscular junction causes thousands of tiny vesicles (pouches) filled with a neurotransmitter called acetylcholine to be released from the axon tip into the synapse.

Detailed explanation-2: -The junction between a motor neuron and muscle fiber is a specialized synapse called the neuromuscular junction. The motor neuron releases a flood of acetylcholine (Ach) neurotransmitters upon stimulation from the axon terminals from synaptic vesicles that bind with the post-synaptic receptors at the plasma membrane.

Detailed explanation-3: -The connection between a motor neuron axon terminal and a muscle fiber occurs at a neuromuscular junction site. This is a chemical synapse where a motor neuron transmits a signal to muscle fiber to initiate a muscle contraction.
