Which item is the navicular?

The item that is the navicular is the small bone known as the distal sesamoid bone, tucked behind the coffin bone inside the hoof. This bone sits at the back of the foot and forms part of the navicular joint with the surrounding bones, and it works with the deep digital flexor tendon as it passes to the pedal bone. The other options describe soft tissues or cartilage, not a bone: collateral cartilage lines the sides of the coffin joint, the extensor tendon runs along the front of the hoof, and chondrocoronal refers to cartilage near the coronary band. Therefore, the term that names a bone—the navicular—is the correct choice.
