MESENTERIC PLEXUS Meaning and
Definition
-
The mesenteric plexus is a complex network of nerve fibers located in the mesentery, a fold of tissue that connects the intestines to the abdominal wall. It is part of the autonomic nervous system, which regulates various involuntary functions of the body.
The mesenteric plexus is composed of both sympathetic and parasympathetic nerve fibers. The sympathetic fibers originate from the spinal cord's thoracic and lumbar regions and travel through the sympathetic chain ganglia to reach the mesenteric plexus. These fibers primarily have an inhibitory effect on the digestive system, decreasing the activity of the smooth muscles in the intestines and reducing blood flow to the abdominal organs.
On the other hand, the parasympathetic fibers of the mesenteric plexus arise from the vagus nerves, which originate in the brainstem. These fibers have a stimulatory effect on the digestive system, increasing the activity of the smooth muscles in the intestines and promoting blood flow to the abdominal organs.
The mesenteric plexus also contains sensory fibers that transmit information about pain, temperature, and other sensations from the abdominal organs to the central nervous system. Additionally, it communicates with other plexuses in the abdomen, such as the celiac plexus, to coordinate the functioning of the various organs involved in digestion.
Overall, the mesenteric plexus plays a crucial role in regulating the digestive processes and maintaining the proper functioning of the abdominal organs.

Etymology of MESENTERIC PLEXUS
The word "mesenteric plexus" is derived from two main components: "mesenteric" and "plexus".
1. "Mesenteric" comes from the Latin word "mesenterium", which refers to the membrane connecting the intestines to the posterior abdominal wall. It is derived from the Greek word "mesos" meaning "middle" and "enteron" meaning "intestine". The term was first used in the 14th century and later evolved to specifically refer to the mesentery.
2. "Plexus" originates from the Latin word "plexus", which means "braid" or "network". It is derived from the past participle of "plectere", meaning "to weave or braid". In the context of anatomy, "plexus" refers to a network of nerves, blood vessels, or lymphatic vessels.
