What is the anatomical term for the second joint of a rabbit's leg?

The anatomical term for the second joint of a rabbit's leg is the hock. In rabbits, the limb structure is adapted for both running and jumping, and this is where the hind leg's anatomy differs significantly from that of humans and other animals. The hock is analogous to the human ankle and is located between the knee, which is the first joint of the rabbit's leg, and the foot.

Understanding the function of the hock is key in rabbit anatomy, as it plays a crucial role in locomotion, providing the necessary leverage for powerful jumping and sprinting. The use of the term "hock" specifically distinguishes this joint from other joints in the leg, such as the elbow (which is found in the front legs), knee (the first joint of the hind leg), and wrist (located in the front legs). This clarity in anatomical terminology is essential for proper communication in veterinary care and rabbit husbandry.
