Solution

The correct option is D
The calcium causes the release of acetylcholine

The tiny gap between the innervating neuron and the sarcolemma of the muscle fibre it is innervating, is called the neuromuscular junction or the motor end plate. this is a junction between the points of contact of an axon terminals of the neuron and the motor end plate of a skeletal muscle.

Q. Assertion :A neuron chemically communicates with a myocyte by releasing acetylcholine into the myoneural junction. Reason: Acetylcholine diffuses across the nerve-muscle synaptic-cleft and binds to receptors on the sarcolemma which gets depolarized.
