Question

define Atresia of vagina.

Answer 1

Failure of canalization of the vaginal plate re­sults in vaginal atresia. The vaginal lu­men is absent in the lower two-thirds, where the vagina is represented by a bansverse septum. However, the open­ing of the cervix uteri is surrounded by a small vaginal pouch, indicating that the upper one-third of the vagina is de­rived from the paramesonephric ducts.
