Answer
A deep cut to the ring finger that results in an inability to move the metacarpophalangeal (MCP) joint indicates damage to the nerves supplying the muscles responsible for both flexion and extension of this joint.
- Muscles for MCP joint movement of the ring finger:
- Flexion: The flexor digitorum superficialis (median nerve) and flexor digitorum profundus (median and ulnar nerves for the ring finger) contribute to flexion. The lumbricals (medial two by ulnar nerve, lateral two by median nerve) and interossei (ulnar nerve) are also crucial for MCP flexion and fine motor control.
- Extension: The *ext
