Which limb is described as having more weight-bearing support and more check ligaments?

• A. Pelvic
• B. Thoracic
• C. Forelimb
• D. Hind limb

Answer: (B)

The thoracic limb (forelimb) is the one described. In the stay apparatus, the forelimbs bear a larger share of the body’s weight when standing and rely on multiple check ligaments to restrain the flexor tendons, helping to keep the limb extended with minimal muscular effort. These check ligaments act as passive supports, enabling the animal to remain upright and stable. The hind limb, while strong for propulsion, isn’t described as providing the primary weight-bearing support in this context, and the forelimb’s arrangement with more check ligaments is what’s being highlighted.
