ARTERIA COLICA DEXTRA Meaning and
Definition
-
Arteria Colica Dextra is a Latin term used in the field of anatomy and medicine to refer to the right colic artery. It is an important blood vessel that supplies oxygenated blood to the ascending colon, a part of the large intestine.
The right colic artery arises from the superior mesenteric artery, which is a major branch of the abdominal aorta. It runs in close proximity to the ascending colon, along its medial border. As it progresses, the arteria colica dextra gives off several branches that penetrate and supply blood to the ascending colon. These branches include the ascending branch, which runs upward in the colonic wall, and the posterior and anterior branches, which anastomose (connect) with other arteries in the region to provide collateral circulation.
The arteria colica dextra plays a crucial role in maintaining the blood supply to the ascending colon, which is responsible for the absorption of water and electrolytes, as well as the formation of stool. A compromised blood flow through this artery can lead to ischemia (reduced blood supply) of the ascending colon, resulting in various complications such as colonic necrosis or infarction.
Understanding the anatomy and function of the arteria colica dextra is essential for healthcare professionals, particularly surgeons, who may need to assess, repair, or ligate this artery during surgical procedures involving the ascending colon.
