Horizontal abduction and horizontal adduction of the shoulder (transverse plane) Medial and lateral rotation of the shoulder (also known as internal and external rotation). Medial rotation is carried out by the anterior fibres of the deltoid, teres major, subscapularis, pectoralis major and the latissimus dorsi.
The human shoulder is made up of three bones: ... Arm adduction [14] Arm adduction is the opposite motion of arm abduction. ... The horizontal alignment of the ...
Adduction is an anatomical term of motion referring to a movement which brings a part of the anatomy closer to the middle sagittal plane of the body. Upper limb [ edit ]
Adduction is a motion that pulls a structure or part towards the midline of the body, or towards the midline of a limb, carried out by one or more adductor muscles. In the case of fingers and toes, it is bringing the digits together, towards the centerline of the hand or foot.
It is thus opposed to adduction. Upper limb. Arm and shoulder. of arm at shoulder (raising arm) [1] [2] Supraspinatus 0-15; Deltoid 15-90; Hand and wrist
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. It also has a synergistic role in extension and lateral flexion of the lumbar spine.
They work in tandem with the posterior deltoid to externally (laterally) rotate the humerus, as well as adduction. Teres Minor can produce only very small scapular plane adduction during maximal contraction (Hughes RE, An KN 1996) with adductor moment arm of approximately 0.2 cm at 45° of shoulder internal rotation and approximately 0.1 cm at ...
The most important ligament involved in shoulder joint stability is the Inferior Glenohumeral Ligament. During abduction of the arm, the middle and inferior ligaments become taut while the superior ligament relaxes. The radius of curvature of the head of the humerus is greater superiorly than inferiorly, which further stretches these ligaments ...
