Q
A

deltoid

ABDUCTS THE ARM

The deltoid is formed of acromial, clavicular and scapular spinal parts. Acromial part (middle fibres) abducts the arm, while the clavicular and scapular spinal parts play a significant role in stabilization, ensuring a steady plane of abduction. Additionally, the clavicular part (anterior fibers) can act as a flexor and internal rotator of the arm, while the scapular spinal part (posterior fibers) can extend and externally rotate the arm.
