is a rapid change in the electrical potential of the membrane of a nerve or muscle cell, allowing for the transmission of signals.

Synaptic Vesicles

Small sacs in a synapse that release neurotransmitters into the synaptic cleft to transmit signals between neurons.

Neurons

Nerve cells specialized for transmitting electrical and chemical signals throughout the body and brain.

Synapse

a structure that permits a neuron (nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell.
