Which of the following accurately pairs the type of receptor to the stimuli in which it responds?

A. Chemoreceptor-pressure

B. Photoreceptor-chemicals

C. Pain receptor-tissue injury

D. Mechanoreceptor-temperature

C. Pain receptor-tissue injury

Neuroreceptors are found all over one's body and epithelial tissues to detect and be aware of the external stimuli

Receptor proteins are molecules inside a cell or on its surface on which ligands bind. A ligand is any substance (e. g. a hormone, drug, functional group) that binds specifically and reversibly to another chemical entity to form a large complex. Receptor proteins found inside a cell are called internal receptors or intracellular receptors or cytoplasmic receptors.
