Which ligament is described as the side branch ligaments between the hand bones and finger bones?

• A. Side branch ligaments between hand bones and fingerbones
• B. Collateral metacarpophalangeal ligaments
• C. Inferior pubic ligament
• D. Round surface for ligament between coracoid process and collarbone

Answer: (B)

Joints between the hand bones and finger bones are the metacarpophalangeal joints, and the side ligaments here are the collateral ligaments. These are the collateral metacarpophalangeal ligaments that run along the radial and ulnar sides of each MCP joint, connecting the metacarpal head to the base of the proximal phalanx. They provide lateral stability, limiting sideways (abduction/adduction) movement and helping the finger stay aligned during grasp. They’re especially tight when the finger is flexed, which helps prevent sideways slipping as you grip. The other options refer to structures unrelated to the hand-to-finger joints, such as ligaments in the pelvis or a shoulder-area ligament, so they don’t describe the side ligaments that stabilize the metacarpophalangeal joints. The general idea of side ligaments between hand bones and finger bones is best captured by the collateral metacarpophalangeal ligaments.
