Which anatomical structures are found in the front limb of the horse?

The front limb of a horse includes several critical anatomical structures, specifically those that support movement and weight-bearing. The carpus, metacarpus, and radius are all essential components found within the horse's front limb.

The carpus, commonly referred to as the knee in horses, is a complex joint that consists of several small bones that connect the forearm to the hand. It plays a crucial role in the flexibility and movement of the horse’s front leg as it navigates different terrains.

Next, the metacarpus comprises the long bones of the mid-leg, helping to bear weight and providing additional support as the horse moves. The metacarpal bones are structurally designed to absorb the stresses associated with galloping and jumping.

Finally, the radius is one of the two primary bones in the forearm (with the ulna being the other, though it is much less developed in horses). The radius supports the forelimb and is involved in the movement and articulation of the carpus.

In summary, the selection highlights the key bones that are part of the skeletal framework of the horse's front limb, emphasizing their roles in locomotion and structural integrity.
