The proximal check ligament is which of the following?

The proximal check ligament is which of the following?

• A. DDF
• B. SDF
• C. Interosseous muscle
• D. Suspensory ligament

Answer: (B)

The proximal check ligament is a band that ties the superficial digital flexor tendon to the nearby proximal structures, helping to convert tendon tension into support for the fetlock. In the stay apparatus, this connection to the SDF tendon provides the dorsal-locked tension that allows the limb to bear weight with little muscular effort. That’s why the correct choice is the superficial digital flexor tendon. The deep digital flexor tendon forms the distal check ligament, the suspensory ligament is a separate major component along the back of the limb, and the interosseous muscle is not the proximal check ligament.
