Question

A baby failed to pass meconium. The structures absent in the disease are absent in which layer?

• A. Epithelial
• B. Submucosa
• C. Muscular
• D. Serosa

Hint:

In Hirschsprung disease, the absence of ganglion cells in the submucosal and myenteric plexuses leads to colonic dysfunction and failure to pass meconium.

Answer 1

The Correct Option is B

Failure to pass meconium is commonly seen in Hirschsprung disease, which involves the absence of ganglion cells in the submucosal and myenteric plexuses. The defect in these structures results in impaired peristalsis, leading to bowel obstruction and the inability to pass meconium.
