Insight into the Interosseous Muscles

This 10-part series explores multidimensional influence the interosseous muscles have on finger movement.

Increase your appreciation of the multidimensional influence the interosseous muscles have on finger movement by examining detailed anatomy and kinesiology, including the varied role of the muscles depending on the position of the metacarpophalangeal joint. Expand your insight into the role of these muscles in MP joint flexion, PIP joint extension, and DIP joint extension as well as abduction/adduction and rotation of the finger.
