Arm extension

Arm extension represents the opposite movement to arm flexion where the arm moves posteriorly. Only about 40° of movement posteriorly from the anatomic position is achievable in most individuals. It is the opposite of arm flexion and contributes to the combined movement of shoulder circumduction.

It is produced by:

  • deltoid (posterior fibers)
  • latissimus dorsi
  • teres major
