🩺 Vermiform Appendix

✅ Answer: (C) Cecum

📖 What is the Vermiform Appendix?

Vermiform = Worm-shaped.
Appendix = A narrow, finger-like pouch attached to the large intestine.

👉 The vermiform appendix is a small, worm-like tube arising from the posteromedial wall of the cecum, just below the ileocecal valve.

📖 What is the Cecum?

Cecum is the first part of the large intestine.

👉 It receives food from the ileum (last part of the small intestine) through the ileocecal valve. The appendix is attached to the cecum.

🩺 Why is Option (C) Correct?

The vermiform appendix:

• ✔ Arises directly from the cecum
• ✔ Is located in the right lower quadrant (RLQ) of the abdomen
• ✔ Contains abundant lymphoid tissue
• ✔ Can become inflamed, causing appendicitis

👉 Therefore, the correct answer is (C) Cecum.

❌ Why Other Options Are Wrong?

(A) Duodenum
❌ The duodenum is the first part of the small intestine and has no connection with the appendix.

(B) Ileum
❌ The ileum is the last part of the small intestine. Although it opens into the cecum, the appendix is attached to the cecum, not the ileum.

(D) Ascending Colon
❌ The ascending colon begins after the cecum. The appendix does not arise from the ascending colon.

📝 Parts of the Large Intestine

📌 Exam Tip: The vermiform appendix is attached to the cecum, approximately 2 cm below the ileocecal valve. Pain from acute appendicitis typically begins around the umbilicus and later localizes to McBurney’s point in the right lower abdomen.
