Mesocolon is a medical term used to refer to the portion of the colon that connects to the abdominal wall. Its spelling is based on the roots "meso-" meaning middle and "colon" meaning the large intestine. The word is pronounced /ˌmɛz.əʊˈkəʊ.lən/ with the first syllable stressed and the "o" in "meso" pronounced as "oh." The "c" in "colon" is pronounced as "k" and the final "on" is pronounced as "ən." The correct spelling of medical terms is essential for clear communication in healthcare.
Mesocolon is a term used in anatomy to refer to a structure within the human body, specifically in the abdominal cavity. It is a fold of peritoneum, a thin layer of tissue that lines the abdominal organs, extending from the colon (the large intestine) to the posterior abdominal wall. The mesocolon serves to support and hold the colon in place within the abdominal cavity.
There are different regions of the mesocolon, each related to a different portion of the colon. For example, the transverse mesocolon connects the transverse colon to the posterior abdominal wall, while the sigmoid mesocolon connects the sigmoid colon to the posterior wall. The mesocolon possesses a rich blood supply, which provides nourishment to the colon.
The mesocolon also serves another important function: it contains and protects the blood vessels, lymphatic vessels, and nerves that supply the colon. These vessels and nerves are embedded within the mesocolon, allowing for their safe transportation and distribution throughout the colon.
Understanding the anatomy and function of the mesocolon is crucial in medical fields such as surgery, where knowledge of the structure is necessary in performing procedures involving the colon or diagnosing certain conditions related to this area of the digestive system.
In anat., that part of the mesentery to which the colon is attached.

The word "mesocolon" is derived from the combination of two Greek words: "meso" (μεσο) meaning "in the middle" or "middle", and "kolon" (κωλον) meaning "colon". Together, "mesocolon" refers to the fold of the peritoneum that attaches part of the colon to the posterior abdominal wall. This term is commonly used in medical and anatomical contexts.
