Summary Introduction

To review:

The function of each component of the neuromuscular junction.

Introduction:

A neuromuscular junction is formed by the motor neuron, and the synapses formed by the muscle fibers. The muscle fibers receive the nerve impulses from the motor neurons, which leads to their contraction. Each neuromuscular junction is composed of the axon terminal, synaptic cleft, and the motor end plate. The neurotransmitters are the chemical signals that are released at the synaptic cleft by the axon terminals and received by the motor end-plates of the sarcolemma.
