The elbow and knee are located in which region?

• A. Hind leg
• B. Back
• C. Front leg
• D. Tail

Answer: (C)

In four‑legged animals, the joints named elbow and knee are located on the front limb. The elbow is between the upper arm and forearm, and the term knee here refers to the carpal region of the forelimb. The hind limb has its own knee joint called the stifle, so the elbow and knee aren’t in the back leg. The back region and tail aren’t limb regions, so they aren’t correct either. Therefore, the correct region is the front leg.
