The knee joint in quadrupeds, the femorotibial joint, is referred to by which term?

• A. Peritoneal Cavity
• B. Pleural
• C. Stifle
• D. Sacral

Answer: (C)

The term tested is the veterinary name for the knee region in four-legged animals: the stifle. In quadrupeds, the knee-like joint where the femur meets the tibia is called the stifle, and it encompasses the knee area including the femorotibial and femoropatellar joints. The other terms refer to unrelated body regions: peritoneal cavity is the abdominal lining, pleural relates to the lungs, and sacral refers to the sacrum of the spine. Therefore, the stifle is the correct term for the knee joint in quadrupeds.
