Summary Introduction

Introduction:

The neuromuscular junction is the region where motor neuron axon branches come in contact with the muscle fiber. Acetylcholinesterase is a molecule that prevents acetylcholine, a neurotransmitter, from getting accumulated within the synaptic cleft. This does not allow acetylcholine to act as a constant stimulus at the motor-endplate and thereby producing continuous muscle fiber contraction.
