Which statement about the primary function of check ligaments is correct?

• A. Prevent overstretching of tendons
• B. Connect to palmar ligament
• C. Run cranially
• D. Support bone growth

Answer: (A)

Check ligaments act to restrain the flexor tendons so they don’t stretch too far when the limb bears weight. By anchoring the tendons to bone, they convert tendon tension into a stable, passive support that keeps joints from overextending. This allows the limb to stand for long periods with less muscular effort while protecting the tendons from injury from overstretching. The other statements don’t describe what these ligaments do: they don’t primarily connect to the palmar ligament, their role isn’t about a cranial direction, and they aren’t involved in bone growth.
