Final Answer:
The scientific name for the "hock" joint in animals, such as horses, is the "tarsal joint." The hock corresponds to the human ankle joint but is anatomically different.
Step-by-step explanation:
The "hock" joint in animals is the equivalent of the human ankle joint and is scientifically referred to as the "tarsal joint." It is located in the hindlimb, specifically in the tarsus or ankle region of quadrupeds like horses. The joint is essential for supporting the animal's weight and facilitating movements such as walking, running, and jumping.
The tarsal joint consists of bones, ligaments, and other connective tissues that enable the articulation between the tibia and fibula (equivalent to human shinbones) and the tarsal bones. The anatomical structure of the tarsal joint allows for flexibility and stability in the animal's hindlimb movements.
