○​ A) The shoulder has stronger ligaments.
○​ B) The hip joint has a deeper socket.
○​ C) The shoulder has a larger muscle group.
○​ D) The hip joint is less weight-bearing.
2.​ Which ligament prevents the tibia from sliding too far forward in relation to the femur?
○​ A) Posterior Cruciate Ligament (PCL)
○​ B) Medial Collateral Ligament (MCL)
○​ C) Anterior Cruciate Ligament (ACL)

○​ B) Calcaneofibular Ligament (CFL)
○​ C) Anterior Talofibular Ligament (ATFL)
○​ D) Deltoid Ligament
5.​ Why are lateral ankle sprains more common than medial sprains?
○​ A) The lateral ligaments are stronger.
○​ B) The medial malleolus acts as a barrier against inversion.
○​ C) The lateral ligaments are weaker and less structurally robust.
○​ D) The normal range of motion favors eversion.

True or False

shoulder joint.
○​ True
○​ False
7.​ The Posterior Cruciate Ligament (PCL) is stronger than the Anterior Cruciate
Ligament (ACL).
○​ True
○​ False
8.​ The Deltoid Ligament is responsible for preventing excessive inversion of the ankle.
