Appendicular Artery, Anterior View

Description

Arising as a terminal branch of the ileocolic artery, the appendicular artery tracks within the mesoappendix toward the vermiform appendix in an anterior abdominal view of a male pelvis. Proximally, the ileocolic vessel descends from the superior mesenteric artery and divides near the ileocecal junction, with small cecal branches fanning medially and inferiorly while the appendicular branch continues distally along the appendix. Adjacent colonic landmarks such as taeniae coli, haustra, and appendices epiploicae provide orientation, and accompanying veins course in parallel as tributaries of the ileocolic vein. Small autonomic nerve fibers are shown coursing with the mesenteric vessels. A clean map of the right lower quadrant. Appendiceal ischemia matters. During acute appendicitis, inflammation and thrombosis in the appendicular artery can progress to gangrene and perforation, and this single-artery supply explains why delayed presentation can deteriorate quickly even when the serosa initially looks modestly inflamed. For surgeons, the anterior perspective clarifies where the mesoappendix is divided and where clips or energy devices are applied during appendectomy, while also hinting at variant branching patterns that complicate hemostasis near the ileocecal artery. Use this plate for gross anatomy teaching on midgut vascular territories, for operative anatomy modules in general surgery and emergency medicine, or as a figure in a journal review discussing appendicitis, stump appendicitis, and appendiceal bleeding. It also suits patient-facing education when explaining why appendectomy targets the mesoappendix rather than the bowel lumen. Anatomical accuracy verified by SciePro's Medical Advisory Board.
