Final answer:
The radial collateral and ulnar collateral ligaments limit side-to-side movements and resist hyperextension of the elbow joint.
Step-by-step explanation:
The radial collateral and ulnar collateral ligaments limit side-to-side movements and resist hyperextension of the elbow joint. The radial collateral ligament supports the lateral side of the elbow, while the ulnar collateral ligament supports the medial side. These ligaments help stabilize the joint and prevent excessive movement in different directions.
For example, if you try to move your forearm sideways or hyperextend your elbow, these ligaments will limit the movements and prevent excessive strain on the joint.
