Summary Introduction

To determine:

The sequence of events from the arrival of an action potential at the synaptic knob until the release of neurotransmitter into the synaptic cleft.

Concept introduction:

A neurotransmitter is chemical substances which are released by the axon terminals at the time of arrival of the nerve impulses. These neurotransmitters are stored in synaptic vesicles. These vesicles then fuse with the sending membrane which results in the release of neurotransmitter into the synaptic cleft.
