PHYSIOLOGICAL SPHINCTER Meaning and
Definition
-
A physiological sphincter refers to a specialized muscle or group of muscles in the human body that functions to regulate the passage of substances within various anatomical structures. These sphincters are typically found in regions where two structures meet or where a closure mechanism is necessary to prevent the backflow or involuntary movement of fluids or substances.
The primary function of a physiological sphincter is to control the flow of materials through certain organs or tubes, ensuring that they occur in a coordinated and controlled manner. These sphincters are under involuntary control, meaning that they operate without deliberate conscious effort.
Some common examples of physiological sphincters include the lower esophageal sphincter, which is located at the junction of the esophagus and stomach, and helps prevent the reflux of stomach acid into the esophagus. Another is the pyloric sphincter, situated between the stomach and the small intestine, controlling the release of partially digested food into the intestines.
Physiological sphincters are closely associated with the autonomic nervous system, which is responsible for regulating involuntary bodily functions. Their contraction and relaxation are governed by neural signals that are transmitted through this system.
In summary, a physiological sphincter is a specialized muscle or muscle group that acts as a gateway, controlling the flow of substances within the body's various structures. Their primary role is to ensure the organized and regulated movement of materials, preventing unwanted backflow or involuntary passage.

Etymology of PHYSIOLOGICAL SPHINCTER
The word "physiological" comes from the Greek words "physis" which means "nature" and "logos" which means "study" or "knowledge". It refers to the study or knowledge of the functions and processes of living organisms.
The word "sphincter" also has Greek origins, derived from the word "sphingktēr" which means "band" or "sling". In anatomy, a sphincter is a circular muscle that contracts or relaxes to open or close a passage or opening in the body.
Therefore, the term "physiological sphincter" combines these two words to refer to a type of sphincter muscle involved in the natural functioning or normal activity of the body.
