- Pronator teres muscles
Pronator teres muscle is a two-headed flexor and pronator of the forearm, found superficially in the anterior compartment of the forearm.
Summary
- origin
- insertion: lateral surface of the middle-third radius
-
arterial supply
- humeral head: inferior ulnar collateral artery and anterior ulnar recurrent artery
- ulnar head: common interosseous artery
- innervation: median nerve
- action: weak flexor at the elbow joint; strong pronator of the forearm joints
