What you will learn

  • Distinguish extrinsic from intrinsic muscles by location and function.
  • Describe the thenar, hypothenar, lumbrical, and interosseous muscles.
  • Associate each muscle with its attachments, action, and stated innervation.
  • Connect muscular anatomy with functional testing, ultrasound, and surgical planning.

Course outline

  1. From forearm to palm

    An orientation map distinguishes extrinsic motors from the muscle groups located within the hand.

    8 min

  2. Fine motors of the thumb

    The thenar muscles are described through their heads, attachments, actions, and nerve supply.

    Four muscles act on the little finger or the skin along the medial side of the palm.

    16 min

  4. Lumbricals: from flexor to extensor

    Course, pennation, and dual innervation explain the linking role of the four lumbricals.
