    Abduction is an anatomical term of motion referring to a movement which draws a limb out to the side, away from the median sagittal plane of the body. It is thus opposed to adduction . Upper limb

  3. Supraspinatus muscle - Wikipedia

    en.wikipedia.org/wiki/Supraspinatus_muscle

    The supraspinatus muscle performs abduction of the arm, and pulls the head of the humerus medially towards the glenoid cavity. [5] It independently prevents the head of the humerus from slipping inferiorly. [5] The supraspinatus works in cooperation with the deltoid muscle to perform abduction, including when the arm is in an adducted position. [5]

  6. Rotator cuff - Wikipedia

    en.wikipedia.org/wiki/Rotator_cuff

    The shoulder that is injured is placed in a sling and shoulder flexion or abduction of the arm is avoided for 4 to 6 weeks after surgery (Brewster, 1993). Avoiding movement of the shoulder joint allows the torn tendon to fully heal. [24] Once the tendon is entirely recovered, passive exercises can be implemented.

    Extension is carried out by the latissimus dorsi and posterior fibres of the deltoid. Abduction and adduction of the shoulder (frontal plane). Abduction is carried out by the deltoid and the supraspinatus in the first 90 degrees. From 90-180 degrees it is the trapezius and the serratus anterior.

  9. Latissimus dorsi muscle - Wikipedia

    en.wikipedia.org/wiki/Latissimus_dorsi_muscle

    The pair of muscles are commonly known as "lats", especially among bodybuilders. The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction (or horizontal extension), [1] flexion from an extended position, and (medial) internal rotation of the shoulder joint.
