Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The association site of the axon terminal of the motor neuron and sarcolemma of a muscle is called a ____
A
synaptic cleft
B
neuromuscular junction
C
motor end plate
D
neurotranmitter
Explanation: 

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.

Detailed explanation-2: -Answer and Explanation: The gap between the axon terminal of a motor neuron and the sarcolemma of a skeletal muscle cell is known as the neuromuscular junction.

Detailed explanation-3: -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-4: -The neuromuscular junction is analogous to the synapse between two neurons. A nerve fibre divides into many terminal branches; each terminal ends on a region of muscle fibre called the end plate.

Detailed explanation-5: -The area of the sarcolemma on the muscle fiber that interacts with the neuron is called the motor-end plate.
