This specimen displays the metacarpophalangeal/metatarsophalangeal joint, as well as the proximal and distal interphalangeal joints. Details of the articular cartilage and synovial cavities, including the dorsal and palmar/plantar recesses, are well depicted. The hoof is sectioned longitudinally, allowing for the identification of the wall, sole, and digital cushion. On the palmar/plantar aspect, the straight sesamoidean ligament and the deep digital flexor tendon can be identified; the latter can be followed to its insertion on the flexor surface of the distal phalanx, closely associated with the navicular bone and surrounding soft tissues.

• Understand the precise spatial relationship between phalanges, joints, and the hoof capsule in the equine digit.
• Appreciate the course and insertion of the deep digital flexor tendon relative to the distal interphalangeal joint and distal phalanx.
• Visualize how hard and soft tissues integrate to support weight-bearing and locomotion in the horse.

• To teach clinically oriented anatomy of the equine foot, especially structures involved in lameness and distal limb pathology.
• To correlate imaging findings (radiographs, MRI) with real anatomical sections of the distal limb.
• To support discussions on biomechanical function and common disorders of the distal interphalangeal joint and surrounding soft tissues.
