Distal sesamoidean ligaments connect proximal sesamoid bones to which structure?

Distal sesamoidean ligaments connect proximal sesamoid bones to which structure?

• A. Distal phalanx
• B. Proximal phalanx
• C. Metacarpus
• D. Navicular bone

Answer: (A)

Distal sesamoidean ligaments anchor the proximal sesamoid bones to the distal part of the digit, the coffin bone (distal phalanx). They form part of the supportive network that stabilizes the fetlock and coffin joints and helps transfer load from the limb when the toe bears weight. As the deep digital flexor tendon acts, these ligaments keep the distal phalanx aligned with the proximal structures, preventing excessive movement. The navicular bone is a separate structure in this region, and the ligaments in question are specifically attached to the distal phalanx, not to the navicular bone or other listed structures.
