Summary Introduction

To describe: The basic sequence of events taking place at the neuromuscular junction.

Introduction: The nervous system controls the skeletal muscle fiber contraction. It controls the muscle fiber at the neuromuscular junction (NMJ), which is a specialized intracellular connection situated midway along the length of the muscle fiber.

Expert Solution & Answer

Explanation of Solution

The sequence of events taking place at a neuromuscular junction:

The motor neuron presents at the neuromuscular junction’s release acetylcholine (ACh) that alters the permeability of the plasma membrane.
This change permits the entry of positive charges. This in turn generates an action potential or electrical impulse in the sarcolemma.
The action potential or electrical impulse spreads across the muscle fiber’s surface and also into the interior along the transverse or T tubules.
The calcium ion (which are released from the sarcoplasmic reticulum) concentration in the cytoplasm increases, which in turns triggers the muscle fiber contraction.
The acetylcholinesterase (AChE) removes the ACh from motor end plate and synaptic cleft and as a result, the contraction ends.
