A momentary reversal in electrical potential across the cell membrane that occurs when a cell has been activated by a stimulus.

• Electric Potential

A substance contained in a vesicle that transmits nerve impulses across a synapse.

• Norotransmitter

• Neurotransmitter

• Electrotransmitter

• Synoptictransmitter

An automatic and often inborn response to a stimulus that involves a nerve impulse passing inward from a receptor to the spinal cord and thence outward to an effector (as a muscle or gland) without reaching the level of consciousness and often without passing to the brain.
