Receptor may refer to:
*
Sensory receptor
Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. This process is called sensory transduc ...
, in physiology, any neurite structure that, on receiving environmental stimuli, produces an informative nerve impulse
*
Receptor (biochemistry)
In biochemistry and pharmacology, receptors are chemical structures, composed of protein, that receive and Signal_transduction, transduce signals that may be integrated into biological systems. These signals are typically chemical messengers whi ...
, in biochemistry, a protein molecule that receives and responds to a neurotransmitter, or other substance
**
Cell surface receptor
Cell surface receptors (membrane receptors, transmembrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules. They are specialized integra ...
, a receptor on the outer surface of a cell membrane, that takes part in communication between the cell and the outside world
**
Nuclear receptor
In the field of molecular biology, nuclear receptors are a class of proteins responsible for sensing steroids, thyroid hormones, vitamins, and certain other molecules. These intracellular receptors work with other proteins to regulate the ex ...
, a receptor found within cells that is responsible for sensing steroid and thyroid hormones and certain other molecules
**
Immune receptor
An immune receptor (or immunologic receptor) is a Receptor (biochemistry), receptor, usually on a cell membrane, which binds to a Ligand (biochemistry), ligand (usually another protein, such as cytokine) and causes a response in the immune system. ...
, a receptor that occurs on the surface of immunocytes and binds to antigens
*
Receiver (radio)
In radio, radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an ante ...
, a device for the reception of electromagnetic signals.
