  2. Acromion - Wikipedia

    en.wikipedia.org/wiki/Acromion

    The acromion forms the summit of the shoulder, and is a large, somewhat triangular or oblong process, flattened from behind forward, projecting at first lateralward, and then curving forward and upward, so as to overhang the glenoid fossa. [2] It starts from the base of acromion which marks its projecting point emerging from the spine of ...

  3. Shoulder - Wikipedia

    en.wikipedia.org/wiki/Shoulder

    In addition to the four muscles of the rotator cuff, the deltoid muscle and teres major muscles arise and exist in the shoulder region itself. [3] The deltoid muscle covers the shoulder joint on three sides, arising from the front upper third of the clavicle, the acromion, and the spine of the scapula, and travelling to insert on the deltoid ...

  4. Acromioclavicular joint - Wikipedia

    en.wikipedia.org/wiki/Acromioclavicular_joint

    The acromioclavicular ligament, which attaches the clavicle to the acromion of the scapula. Superior acromioclavicular ligament. This ligament is a quadrilateral band, covering the superior part of the articulation, and extending between the upper part of the lateral end of the clavicle and the adjoining part of the upper surface of the acromion.

  5. Rotator cuff - Wikipedia

    en.wikipedia.org/wiki/Rotator_cuff

    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. Passive exercises of the shoulder are movements in which a physical therapist maintains the arm in a particular position, manipulating the rotator cuff without any effort by the patient ...

  6. Scapula - Wikipedia

    en.wikipedia.org/wiki/Scapula

    The two muscles most commonly inhibited during this first part of an overhead motion are the serratus anterior and the lower trapezius. [18] These two muscles act as a force couple within the glenohumeral joint to properly elevate the acromion process, and if a muscle imbalance exists, shoulder impingement may develop.

  7. Coracoid process - Wikipedia

    en.wikipedia.org/wiki/Coracoid_process

    The muscles that are attached are: Pectoralis Minor, Coracobrachialis, and Biceps Brachii. In addition, this structure attaches all the tendons and ligaments together. There are two purposes for this structure: it is the primary hold by which the clavicle is joined to the scapula and alongside the acromion and coraco-acromial tendon, it shapes ...

  8. Shoulder girdle - Wikipedia

    en.wikipedia.org/wiki/Shoulder_girdle

    The five muscles that comprise the function of the shoulder girdle are the trapezius muscle (upper, middle, and lower), levator scapulae muscle, rhomboid muscles (major and minor), serratus anterior muscle, and pectoralis minor muscle. [3] The shoulder girdle consists of the clavicle and the scapula, which serve to attach the upper limb to the ...

  9. Greater tubercle - Wikipedia

    en.wikipedia.org/wiki/Greater_tubercle

    The greater tubercle of the humerus is the outward part the upper end of that bone, adjacent to the large rounded prominence of the humerus head. It provides attachment points for the supraspinatus, infraspinatus, and teres minor muscles, three of the four muscles of the rotator cuff, a muscle group that stabilizes the shoulder joint.
