Description

any of various testing devices or substances as (1)   a pointed metal tip for making electrical contact with a circuit element being checked (2)   a usually small object that is inserted into something so as to test conditions at a given point (3)   a device used to penetrate or send back information especially from outer space or a celestial body (4)   a device (as an ultrasound generator) or a substance (as radioactively labeled DNA) used to obtain specific information for diagnostic or experimental purposes,The receptors are ligand binding factors of type 1, 2 or 3 and protein-molecules that receive chemical-signals from outside a cell. When such chemical-signals couple or bind to a receptor, they cause some form of cellular/tissue-response, e.g. a change in the electrical-activity of a cell. In this sense, am olfactory receptor is a protein-molecule that recognizes and responds to endogenous-chemical signals, chemokinesor cytokines e.g. an acetylcholine-receptor recognizes and responds to its endogenous-ligand, acetylcholine. However, sometimes in pharmacology, the term is also used to include other proteins that are drug-targets, such as enzymes, transporters and ion-channels.
