MICROANATOMY

Detailed explanation-1: -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. It is also a site for many diseases and a site of action for many pharmacological drugs.

Detailed explanation-2: -The neuromuscular junction-where nerves and muscle fibers meet-is an essential synapse for muscle contraction and movement.

Detailed explanation-3: -Towards the end of the axon terminal, closest to the muscle fiber, the tip of the axon terminal enlarges and becomes known as the synaptic end bulb. It is the synaptic end bulb of the motor neuron that comprises the nervous system component of the neuromuscular junction.

Detailed explanation-4: -neuromuscular junction, also called myoneural junction, site of chemical communication between a nerve fibre and a muscle cell. The neuromuscular junction is analogous to the synapse between two neurons.

Detailed explanation-5: -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.
