receptor

Definitions

  • WordNet 3.6
    • n receptor an organ having nerve endings (in the skin or viscera or eye or ear or nose or mouth) that respond to stimulation
    • n receptor a cellular structure that is postulated to exist in order to mediate between a chemical agent that acts on nervous tissue and the physiological response

Century Dictionary and Cyclopedia
  • Interesting fact: There are five million scent receptors located in a human beings nose
    • n receptor A molecular complex of a cell through the union with which alien cell-products or cell-constituents can produce, their specific effects upon the coll. These same receptors, owing to the presence of which the cell is open to attack, when cast off from the cell constitute its most effective defenses. Also called side-chain. See immunity, 5.
    • n receptor In wireless telegraphy, a receiver.
    • n receptor The terminal expansion in skin or mucous membranes of a sensory nerve.
