Chapter 28, Problem 28.62AP

Interpretation Introduction

Interpretation:

The way how a nerve impulse is passed from one neuron to another has to be explained.

Concept Introduction:

Neurotransmitters: Neurotransmitters are chemicals that transmit messages from the nervous system to the target cell. They are the chemical messagers where the electrical signal from the nervous system is travelled from one neuron to another to reach the target cell.

Presynaptic neurons produces neurotransmitters which are stored in the small pockets of presynaptic neurons called vesicles from where the neurotransmitters are released according to the need. After neurotransmitter completes its job, it is immediately removed from the cleft of synapse for preparing the presynaptic neurons to get another impulse.
