re·cep·tor

 (rĭ-sĕp′tər)
n.
1. Physiology A specialized cell or group of nerve endings that responds to sensory stimuli.
2. Biochemistry A molecular structure or site on the surface or interior of a cell that binds with substances such as hormones, antigens, or neurotransmitters or is activated by events such as a change in the concentration of an ion.

receptor

(rɪˈsɛptə)
n
1. (Physiology) physiol a sensory nerve ending that changes specific stimuli into nerve impulses
2. any of various devices that receive information, signals, etc

re•cep•tor

(rɪˈsɛp tər)

n.
1. a protein molecule, usu. on the surface of a cell, that is capable of binding to a complementary molecule, as a hormone, antibody, or antigen.
2. a sensory nerve ending or sense organ that is sensitive to stimuli.
[1900–05]

re·cep·tor

(rĭ-sĕp′tər)
1. A nerve ending specialized to sense or receive stimuli. Skin receptors respond to stimuli such as touch and pressure and signal the brain by activating portions of the nervous system. Receptors in the nose detect odors.
2. A cell structure or site that is capable of combining with a hormone, antigen, or other chemical substance.
