FFA Veterinary Science CDE Practice Test

A genetic structural deformity that results in the lack of opening from the rectum is known as ___________.

1. Cleft Palate

2. Anal Atresia

3. Cryptorchidism

4. Mulefoot

The correct answer is: Anal Atresia

The condition characterized by a genetic structural deformity resulting in the absence of an opening from the rectum is known as anal atresia. This congenital anomaly occurs when the anal opening is either missing or not properly formed, which can lead to serious complications, such as inability to pass stool, requiring surgical intervention. When diagnosing cases with similar terminology, understand that cleft palate refers to a gap in the roof of the mouth, cryptorchidism pertains to undescended testicles, and mulefoot describes a specific hoof deformity in pigs. Each of these conditions is distinct and does not relate to the absence of an anal opening, which is the defining characteristic of anal atresia. Understanding these terms is key in differentiating between various congenital defects in veterinary science.
