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.

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.

aIIbb3 (CD41/CD61)also known as GPIIb-IIIa complex, is present only on the platelets and is the most abundant platelet adhesion receptor. Resting platelets express 80,000-100,000 molecules of aIIbb3 on their surface.9 In addition to the surface receptors, 20,000-40,000 molecules of aIIbb3 are also present in the a-granules, dense granules and on the membranes of open canalicular system of the platelets.
