Anus imperforate

From Biology-Online Dictionary | Biology-Online Dictionary

Anus, imperforate

persistence of the anal membrane, so that the anus is closed. The defect is not always complete; sometimes a narrow opening permits the passage of the bowel contents. When completely imperforate, the anus is seen as a dimple (the proctodeal pit) in the skin of the perineum. The latter condition is often associated with atresia of the lower rectum.
