Plexus on the Middle Colic, Right Colic, and Ileocolic Arteries, Anterior View

Description

Running along the mesenteric border of the colon, a perivascular nerve plexus invests the middle colic artery as it courses within the transverse mesocolon, then continues onto the right colic and ileocolic arteries as they descend toward the hepatic flexure and ileocecal junction. An anterior perspective places the transverse colon superior to the ascending colon, with the right colic territory lateral and the root of the mesentery and ileocolic pedicle trending inferiorly and medially. The arterial arcade and adjacent arterioles are framed against characteristic colonic landmarks, including haustra, taeniae coli, and epiploic appendages. Male visceral anatomy. Clear relationships. Clinically, this perivascular autonomic network corresponds to the superior mesenteric plexus and its periarterial extensions, the pathway for sympathetic vasomotor fibers and visceral afferents that travel with the middle colic, right colic, and ileocolic vessels. The view maps directly onto the surgical planes used in right hemicolectomy and complete mesocolic excision, where central vascular ligation at the ileocolic and middle colic origins risks denervation, bleeding at the superior mesenteric vein, and injury near the gastrocolic trunk. It also supports teaching of referred visceral pain patterns from midgut structures and the way plexiform fibers cluster around vessels rather than running as discrete named nerves. Use this artwork in anatomy and surgical anatomy courses covering the midgut, mesenteric root, and colonic vascular supply, or in textbooks and operative atlases describing lymphadenectomy and pedicle control for right-sided colon cancer. It also suits patient-facing or trainee materials that need a precise correlation between colic arteries and the accompanying nerve network during minimally invasive colectomy planning.
