Answer:

An action potential- is defined as a sudden, fast, transitory, and propagating change of the resting membrane potential

Neurotransmitters- are often referred to as the body's chemical messengers.

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

synaptic gap-The minute space between the cell membrane of an axon terminal and of the target cell with which it synapses. synaptic cleft.

Receptor-receiver: such as. a : a cell or group of cells that receives stimuli : sense organ. b : a chemical group or molecule (such as a protein) on the cell surface or in the cell interior that has an affinity for a specific chemical group, molecule, or virus

Answer:

action potential- the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell.

Neurotransmitters- a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure

synapse- a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.

synaptic gap- The minute space between the cell membrane of an axon terminal and of the target cell with which it synapses

Receptor- an organ or cell able to respond to light, heat, or other external stimulus and transmit a signal to a sensory nerve.
