Definition of receptor in English: receptornoun rɪˈsɛptəriˈsɛptər Physiology 1An organ or cell able to respond to light, heat, or other external stimulus and transmit a signal to a sensory nerve. the retina of the octopus has up to 20 million light receptors Example sentencesExamples - But sharks also detect their prey with sensory receptors that run along their sides.
- However, they have some ability to sense light through receptors in the epidermis.
- In the sea, the krill schools use their highly developed sensory receptors to find food.
- All are viewed dispassionately, the heart as a pump, the brain as a network of neural tissues, the eye as a receptor of visual stimuli.
- Our own skin contains a battery of touch receptors that produce nerve signals when pressed.
- In the special sense organs, such as the eye and the ear, highly specialized receptors respond to light and sound.
- 1.1 A region of tissue, or a molecule in a cell membrane, which responds specifically to a particular neurotransmitter, hormone, antigen, or other substance.
when viruses succeed in binding to cell membrane receptors they still have to enter the cell before they can replicate Example sentencesExamples - Platelet membranes bear a higher density of receptors per surface area than any other blood cell.
- They can also alter circulating estrogen and androgen levels and can affect hormone receptors.
- Finally, the presence of a specific receptor in the target tissue is required for a hormone to have its effect.
- The heaviest people in his study had fewer dopamine receptors than the lightest.
- Cells receive their instructions from the body through hormones and neurotransmitters that bind to receptors on their surface.
- When the neurotransmitter binds with the receptor, the next cell responds accordingly.
- The neurotransmitter and receptor are specific to each other, like a lock and key.
- Hormones work by docking with a specific receptor on a cell, which then responds by turning on genes.
- The interaction of hormones and their associated receptors is highly specific.
Origin Early 20th century: coined in German from Latin receptor, from recept- 'taken back', from the verb recipere (see receive).
