receptor

receptor
1. A cell or group of cells specialized to detect a particular stimulus and to initiate the transmission of impulses via the sensory nerves. The eyes, ears, nose, skin, and other sense organs all contain specific receptors responding to external stimuli (see exteroceptor); other receptors are sensitive to changes within the body (see interoceptor). See also baroreceptor; chemoreceptor; electroreceptor; magnetoreceptor; mechanoreceptor; osmoreceptor; proprioceptor.

2. An area of a plasma membrane, consisting of a specially adapted membrane protein, that can bind with a specific hormone, neurotransmitter, drug, or other chemical, thereby initiating a change within the cell. For example, the binding of protein hormones to receptors of target cells initiates the synthesis of a second messenger inside the cell.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.

receptor

receptor (ri-sep-ter) n.
1. a cell or group of cells specialized to detect changes in the environment and trigger impulses in the sensory nervous system. All sensory nerve endings act as receptors. See exteroceptor, interoceptor, proprioceptor.

2. a specialized area of cell membrane that can bind with a specific hormone (e.g. oestrogen r.), neurotransmitter (e.g. adrenergic r.), drug, or other chemical, thereby initiating a change within the cell.

receptor

receptor A cell or group of cells that are specialized to respond to particular types of stimulus. There are three main types: chemoreceptors, mechanoreceptors, and radioreceptors. A fourth type, electroreceptors, occurs in some teleosts. When the intensity of the stimulus exceeds a threshold the receptor releases an impulse to the neurones connected to it.
