Receptor Cells

Cells in the body that respond to specific stimuli like light or chemicals and transmit signals to other cells.

Primary Receptors

Secondary Receptors

Protein molecules located on cell surfaces or within cells that bind to external signaling molecules after they have interacted with primary receptors, often amplifying the cellular response.

Chemoreceptors

Sensory receptors that respond to chemical stimuli, such as taste, smell, or changes in the blood's chemical composition.
