Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The gap between the axon terminal of a motor neuron and the sarcolemma of a skeletal muscle cell is called the:
A
neuromuscular junction
B
synaptic cleft
C
sarcomere
D
motor unit
Explanation: 

Detailed explanation-1: -In fact, the synaptic cleft between an axon terminal and muscle cell is called a neuromuscular junction.

Detailed explanation-2: -The space between the two is known as the synaptic cleft.

Detailed explanation-3: -There is a small gap between the axon terminal of the presynaptic neuron and the membrane of the postsynaptic cell, and this gap is called the synaptic cleft.

Detailed explanation-4: -The junction between a motor neuron and the sarcolemma of the muscle fibre is called the neuromuscular junction.

Detailed explanation-5: -Synaptic Cleft-the space between the axon terminal and the motor end plate. Axon Terminal-the swollen distal end of the motor neuron axon. Sarcolemma-the muscle cell membrane. Synaptic Vesicles-structures within the axon terminal that contain the neurotransmitter acetylcholine (ACh).
