Receptors that in general do not produce an action potential, but can release neurotransmitters in response to a receptor potential are ________ receptors.

A) phasic
B) primary
C) secondary
D) tonic

Secondary Receptors

Proteins or cellular components that detect signals or substances released by primary receptors and further propagate cellular response.

Receptor Potential

The change in electrical potential across a sensory receptor's membrane that occurs in response to a stimulus, leading to the generation of a nerve impulse.

Neurotransmitters

Chemicals that transmit signals across a synaptic gap between neurons in the nervous system.
