A clean, accurate labeled medical anatomy diagram of Meckel diverticulum in an infant. Show a simple loop of distal ileum, with a blind-ending true diverticulum arising from its antimesenteric border. Include an inset embryology sketch showing the vitelline (omphalomesenteric) duct from ileum to yolk sac normally obliterating, with persistence at the ileal end forming Meckel diverticulum. Use clear labels: Ileum, Meckel diverticulum, antimesenteric border, vitelline duct remnant, yolk sac. Educational textbook diagram.

Meckel diverticulum

Labeled diagram of Meckel diverticulum and its embryologic vitelline duct remnant
Key point: Meckel diverticulum is a blind-ending, true diverticulum on the antimesenteric border of the ileum, caused by incomplete obliteration of the vitelline (omphalomesenteric) duct. The duct normally disappears around the 6th to 7th week of development. This is consistent with the NCBI overview and Merck Manual description.

omphalomesenteric duct remnant umbilical sinus polyp fistula diagram

Generating Image

A clean, hand-drawable medical embryology exam diagram containing three separate labeled panels of omphalomesenteric (vitelline) duct remnants. Panel 1: Umbilical sinus, showing an ileal loop at bottom, a short blind-ending tract extending inward from the umbilicus but not reaching ileum. Panel 2: Umbilical polyp, showing a small red mucosal nodule at the umbilicus with no tract to ileum. Panel 3: Patent omphalomesenteric duct or umbilical-enteric fistula, showing a continuous open tract from ileum to umbilicus with arrow showing fecal discharge. Include one consistent orientation in every panel: umbilicus at top, ileum at bottom. Simple black line educational textbook illustration, labels only: Umbilicus, Ileum, blind sinus tract, umbilical polyp, patent vitelline duct, fecal discharge.

Vitelline duct remnants: diagrams to draw

Umbilical sinus, umbilical polyp, and patent vitelline duct fistula diagrams
Copy them as three small side-by-side sketches:
  1. Umbilical sinus
    • Draw umbilicus at the top and ileum at the bottom.
    • Draw a short blind tract going inward from the umbilicus.
    • It does not reach the ileum.
    • Label: Umbilical sinus, blind sinus tract, ileum.
  2. Umbilical polyp
    • Draw only a small rounded red/pink nodule at the umbilicus.
    • No connection to ileum.
    • Label: Umbilical polyp.
  3. Umbilical fistula / patent vitelline duct
    • Draw a continuous tube from umbilicus to ileum.
    • Add an outward arrow at the umbilicus: fecal discharge.
    • Label: Patent vitellointestinal (omphalomesenteric) duct / umbilical fistula.
A patent duct communicates between the ileum and umbilicus; a sinus is blind-ended at the umbilical side, while an umbilical polyp is ectopic intestinal or gastric mucosa at the umbilicus without a patent tract. This remnant spectrum is described in StatPearls embryology.
