Definitions:

Action Potential

A rapid change in electrical potential across the membrane of a nerve or muscle cell when it is stimulated, leading to transmission of an electrical impulse.

Gap Junctions

Specialized intercellular connections that allow for the direct transfer of ions and molecules between neighboring cells, facilitating communication and coordination of activity.

Electrical Synapses

A type of synapse in which electrical currents flow directly from one cell to another via gap junctions, facilitating rapid communication.

Presynaptic Terminal

The end part of a nerve cell (neuron) that releases neurotransmitters to send a signal across the synapse to another neuron.
