Question

receptors means what

Answer 1

Medical Definition of Receptor

Receptor: 1. In cell biology, a structure on the surface of a cell (or inside a cell) that selectively receives and binds a specific substance. There are many receptors. There is a receptor for (insulin; there is a receptor for low-density lipoproteins (LDL); etc. To take an example, the receptor for substance P, a molecule that acts as a messenger for the sensation of pain, is a unique harbor on the cell surface where substance P docks. Without this receptor, substance P cannot dock and cannot deliver its message of pain. Variant forms of nuclear hormonereceptors mediate processes such as cholesterol metabolism and fatty acidproduction. Some hormone receptors are implicated in diseases such as diabetes and certain types of cancer. A receptor called PXR appears to jump-start the body's response to unfamiliar chemicals and may be involved in drug-drug interactions.
2. In neurology, a terminal of a sensorynerve that receives and responds to stimuli.

Answer 2

Receptors: An organ or cell able to respond light, heat, or other external stimulus and transmit a signal to a sensory nerve.
