Question

At the neuromuscular junction, the muscle fiber membrane is folded to form a

A) motor end plate.
B) motor unit.
C) neuroreceptor
D) neurotransmitter.
E) motor neuron.

Answer 1

The correct answer will be option-A.

Step-by-step explanation:

The neuromuscular junction is the junction at which the motor neurons brings the signals to form the CNS to cause the response.

The motor neurons carry the signals in the form of action potential and have to pass on this information to the muscles. The muscle cells of muscle fibers receive these signals form motor neuron at this junction by modifying the ends of its structure by folding its end. This folded structure is known as the "motor end plate" which receives the signals and transfers the same to the sarcomere and causes the muscle contraction.

Thus, option-A is the correct answer.
