TRISPLANCHNIC NERVE Meaning and
Definition
-
The trisplanchnic nerve is a term used in anatomy to refer to a group of nerves associated with the innervation of the abdominal organs. The word "trisplanchnic" is derived from the Latin roots "tri-" meaning three and "splanchnic" which refers to the viscera or internal organs.
The trisplanchnic nerve is composed of three major branches: the greater splanchnic nerve, the lesser splanchnic nerve, and the least splanchnic nerve. Each of these branches arises from different levels of the sympathetic nervous system, specifically the thoracic region of the spinal cord.
The greater splanchnic nerve arises from the sympathetic chain at approximately the fifth to ninth thoracic level, while the lesser splanchnic nerve arises from the tenth and eleventh thoracic levels. The least splanchnic nerve originates from the twelfth thoracic level.
These nerves pass through the diaphragm and innervate various abdominal organs, including the stomach, liver, gallbladder, spleen, and intestines. They carry sympathetic fibers that regulate various functions, such as blood flow, glandular secretions, and smooth muscle contractions within these organs.
Understanding the trisplanchnic nerve and its branches is essential in comprehending the complex innervation and regulation of the abdominal organs within the autonomic nervous system.

Etymology of TRISPLANCHNIC NERVE
The term "trisplanchnic nerve" is derived from the combination of the Greek words "tris" meaning "three" and "splanchon" meaning "viscera" or "internal organs". The word "nerve" comes from the Latin word "nervus", meaning "sinew, tendon, or cord". Therefore, the etymology of "trisplanchnic nerve" pertains to a nerve that is associated with three internal organs or viscera in the body.
