POSTSYNAPTIC RECEPTOR Meaning and
Definition
-
A postsynaptic receptor refers to a specialized protein molecule found on the surface of a nerve cell, specifically located in the postsynaptic membrane. It acts as a receptor site for neurotransmitter molecules, which are chemical messengers released by adjacent neurons. The binding of neurotransmitters to postsynaptic receptors triggers specific physiological responses in the receiving or postsynaptic neuron.
Postsynaptic receptors play a vital role in signal transmission between neurons in the central and peripheral nervous system. Upon the release of neurotransmitters into the synapse, they diffuse across the synaptic cleft and attach to the corresponding postsynaptic receptors. This binding activates the receptor, initiating a series of biochemical changes within the postsynaptic neuron.
These receptors are classified into various subtypes depending on their properties and mode of action. Each receptor subtype selectively recognizes specific neurotransmitters, facilitating a diverse range of signaling pathways. Examples of postsynaptic receptors include the G-protein coupled receptors (GPCRs) and ionotropic receptors, such as the ligand-gated ion channels.
The activation of postsynaptic receptors can result in the generation of electrical impulses or changes in intracellular signaling cascades, leading to the modulation of neurotransmission. This modulation ultimately determines the strength and direction of the neural circuit, influencing the overall function and communication within the nervous system.
Understanding the role and function of postsynaptic receptors is essential in deciphering the intricacies of neuronal communication and provides insights into the development of therapies targeted at neurological disorders.

Etymology of POSTSYNAPTIC RECEPTOR
The term "postsynaptic receptor" is composed of two parts: "postsynaptic" and "receptor".
The term "postsynaptic" refers to the location of the receptor, which is after (post) the synapse - the tiny gap between nerve cells where they communicate with each other. It describes the side of the synaptic cleft that receives the neurotransmitter signals.
The word "receptor" comes from the Latin word "receptus", which means "to receive". In the context of neuroscience, a receptor is a specialized protein molecule located on the surface of a cell that can bind to specific molecules, such as neurotransmitters or hormones, and initiate a biochemical response within the cell.
In summary, "postsynaptic receptor" refers to a receptor located on the side of the synapse that receives neurotransmitter signals, enabling communication between nerve cells.
