GENERAL HISTOLOGY

Detailed explanation-1: -Answer and Explanation: The axon terminal of a motor neuron “connects” with the muscle fiber at a place called the neuromuscular junction|], (In general, a motor neuron and the muscle fibers under its control are called a motor unit.)

Detailed explanation-2: -A neuromuscular junction exists between the axon terminal and the motor end plate of a muscle fiber where neurotransmitters are released.

Detailed explanation-3: -At this point, each axon of the motor neuron will divide into branches called axon terminals. Towards the end of the axon terminal, closest to the muscle fiber, the tip of the axon terminal enlarges and becomes known as the synaptic end bulb.
