The origin of the deep digital flexor tendon is from which muscles?

The deep digital flexor tendon is formed from the deep flexor muscle group. In the forelimb, the deep flexor muscles lie on the caudal side and their muscle bellies give rise to the tendon that runs down the limb to insert on the distal phalanx, enabling flexion at the distal interphalangeal joint. The other options don’t contribute to this tendon: interosseous muscles are part of the suspensory system, extensor muscles form the dorsal (extensor) tendons, and the superficial flexor muscles give rise to the superficial digital flexor tendon, not the deep one.
