ANATOMY

Detailed explanation-1: -The area of synaptic contact between motor neurons and their target muscle fibers is the neuromuscular junction (NMJ). This synapse occurs at a specialized area of the sarcolemma called the endplate (Figure 1).

Detailed explanation-2: -It is the synaptic end bulb of the motor neuron that comprises the nervous system component of the neuromuscular junction. The muscular component is a region of the muscle fiber referred to as the motor end plate.

Detailed explanation-3: -Where the tip of each axon comes into proximity with a muscle fibre, it forms a synapse with that fibre. This special form of synapse between a motor neuron axon and a muscle fibre is called a neuromuscular junction.

Detailed explanation-4: -The place where a neuron makes contact with an individual muscle fiber is called a neuromuscular junction. The neuromuscular junction is basically a synapse: the neuron releases a neurotransmitter called acetylcholine (ACh) which binds to receptors on the sarcolemma (the cell wall of the muscle fiber).

Detailed explanation-5: -Neuromuscular junctions (NMJs) are excitatory chemical synapses formed between nerve terminals of spinal cord motor neurons and skeletal muscle fibers that use acetylcholine as the neurotransmitter.
