The coracoid process acts as an attachment and origin for a large number of muscles (attached muscles not labeled here). The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; [2] it runs at first upward and medially; then, becoming smaller, it changes its direction, and projects forward and laterally.
The coracoacromial ligament is a strong triangular ligament between the coracoid process and the acromion. It protects the head of the humerus . Its acromial attachment may be repositioned to the clavicle during reconstructive surgery of the acromioclavicular joint (shoulder joint).
The coracohumeral ligament arises from the lateral border or the base of the coracoid process. [1] [2] It passes obliquely downwards and laterally to the front of the greater tubercle of the humerus. [1] [2] It forms two bands [3]: 908 - an anterior one and a posterior one - that insert into the lesser and greater tubercles of the humerus ...
The coracoclavicular ligament connects the clavicle to the coracoid process of the scapula. [1] It is not part of the acromioclavicular joint articulation, but is usually described with it, since it keeps the clavicle in contact with the acromion. It consists of two fasciculi, the trapezoid ligament in front, and the conoid ligament behind. [2]
Palpation of coracoid process of scapula [5] The coracoid process of the scapula is not subcutaneous; It is covered by the anterior border of the deltoid. However, the tip of the coracoid process can be felt on deep palpation on the lateral aspect of the clavipectoral triangle. The coracoid process is used as a bony landmark when performing a ...
A coracoid [a] is a paired bone which is part of the shoulder assembly in all vertebrates except therian mammals (marsupials and placentals). In therian mammals (including humans ), a coracoid process is present as part of the scapula , but this is not homologous with the coracoid bone of most other vertebrates.
When the pectoralis minor is inserted, as occasionally is the case, into the capsule of the shoulder-joint instead of into the coracoid process, it passes between these two bands, and the intervening portion of the ligament is then deficient. The coracoclavicular ligament, which consists of two ligaments, the conoid and the trapezoid ligaments.
Runs laterally over the coracoid process and under the deltoideus, to which it gives branches; it then pierces that muscle and ends on the acromion in an arterial network formed by branches from the transverse scapular (a.k.a. suprascapular), thoracoacromial, and posterior humeral circumflex arteries. Clavicular branch
