Which ligament forms the lateral support of the metacarpophalangeal joints, connecting the metacarpal bones to the finger bones?

The MCP joints need side-to-side stability to resist sideways forces during grip, and that stability comes from the collateral metacarpophalangeal ligaments. These ligaments run along the radial and ulnar sides of each MCP joint, connecting the metacarpal heads to the bases of the proximal phalanges, and they limit abduction and adduction of the finger—especially when the finger is flexed—providing the lateral support the joints require. The other options relate to different joints or structures: the transverse carpal ligament is at the wrist forming the carpal tunnel roof, the anterior sternoclavicular ligament is at the sternoclavicular joint, and the proximal radioulnar joint is in the forearm.
