The appendix is attached to which major region of the large intestine?

• A. Cecum
• B. Colon
• C. Rectum
• D. Sigmoid colon

Answer: (A)

The main idea is that the vermiform appendix is a blind tube that arises from the cecum, the first pouch-like section of the large intestine. It attaches to the posteromedial wall of the cecum, just below the ileocecal valve. Because of this direct origin, the appendix is associated with the cecum rather than with the colon proper, the rectum, or the sigmoid colon. The colon proper begins after the cecum, the rectum is farther downstream, and the sigmoid colon is a more distal segment, so none of them serve as the origin for the appendix.
