Which bone does the SDF tendon terminate at?

Explanation:
The superficial digital flexor tendon (SDF) ends on the middle phalanx, the bone in the pastern region. As the SDF travels down the forelimb, its fibers insert on the palmar aspect of this middle bone, allowing flexion at the proximal interphalangeal joint and contributing to the stay apparatus. The deep digital flexor tendon, by comparison, attaches to the distal phalanx (the coffin bone). The navicular bone lies along the tendon’s path but is not the endpoint of the SDF. So, the termination at the pastern bone is the correct understanding.
