CHOLECYSTOKININ RECEPTORS Meaning and
Definition
-
Cholecystokinin receptors, also known as CCK receptors, are cell membrane proteins that are involved in the regulation of various physiological processes within the body. These receptors specifically bind to and interact with the neuropeptide cholecystokinin (CCK), a hormone that is synthesized and released by cells in the gastrointestinal tract and central nervous system.
Cholecystokinin receptors are primarily found in the gastrointestinal tract, including the gallbladder and pancreas, as well as in the central nervous system, such as the brain and spinal cord. There are two main types of CCK receptors, known as CCK1 and CCK2 receptors, which are further categorized into different subtypes.
Activation of CCK receptors by binding to CCK peptides triggers a range of physiological responses. In the gastrointestinal tract, CCK receptors regulate the release of digestive enzymes from the pancreas, the contraction of the gallbladder to facilitate the release of bile, and the regulation of gastric emptying. In the central nervous system, CCK receptors are involved in the modulation of emotions, pain perception, and feeding behavior.
The dysfunction of cholecystokinin receptors has been associated with various medical conditions, such as gallstone formation, pancreatic disorders, and mental health disorders including anxiety and schizophrenia. Thus, understanding the role and function of cholecystokinin receptors is crucial for developing potential therapeutic strategies for these conditions.
In summary, cholecystokinin receptors are cell membrane proteins that bind to and interact with the cholecystokinin hormone, playing a crucial role in the regulation of physiological processes in the gastrointestinal tract and central nervous system.

Etymology of CHOLECYSTOKININ RECEPTORS
The word "cholecystokinin receptors" is a combination of several components:
1. Cholecystokinin: The term "cholecystokinin" is derived from the Greek words "chole" meaning "bile", "cysto" meaning "bladder", and "kinin" meaning "to move". Cholecystokinin is a peptide hormone that is released by cells in the duodenum (first part of the small intestine) in response to the presence of fat and protein in the digestive tract. It plays a role in regulating digestion, appetite, and satiety.
2. Receptors: The term "receptors" is derived from the Latin word "receptus", which means "taken back".
