Anatomy & Physiology: Muscles—Flexor Digiti Minimi (fingers).
Structure.
- Origin: flexor retinaculum and hamate.
- Insertion: medial side of proximal phalanx of little finger.
Function.
- Concentric action: flexes pinky finger at carpometacarpal and metacarpophalangeal joints.
- Reverse mover action: flexion of 5th metacarpal at MCP; distally glide the hamate at 5th CMC joint.
- Eccentric action: controls/restrains/slows the CMC and MCP joints of little finger.
- Isometric action: stabilize CMC and MCP of little finger.
- Innervation: ulnar nerve.
- Arterial supply: branches of ulnar artery.
