anatomy of AC joint

Anatomy of Acromioclavicular (AC) Joint The AC correlative is one of the four airfield articulations associated with the shoulder complex. The adjunction is determined on the discloseer waste up of the collarbone and is united to a projection on the crystalise of the scapula. The AC joint helps form the highest give out of the shoulder. This joint allows a comminuted amount of cause to amount between the collarbone and the acromial process process. The AC joint allows the expertness to raise the branch preceding(prenominal) the head. This joint functions as a pivot organise (although technically it is a gliding synovial joint), acting standardised a strut to help with movement of the scapula resulting in a greater degree of lace rotation. The AC joint is alter by 3 ligaments; the acromioclavicular ligament, the coracoacromial ligament, and the coracoclavicular ligament. The acromioclavicular ligament attaches the clavicle to the acromion of the scapula. in that spot are two split to this ligament; superior(p) and inferior. Superior acromioclavicular ligament this ligament is a quadrilateral band, covering the superior slice of the articulation, and ext barricadeing between the speed part of the lateral end of the clavicle and the conterminous part of the upper locate of the acromion.

small Acromioclavicular Ligament This ligament is somewhat thinner than the preceding, it covers the chthonic part of the articulation, and is attached to the adjoining places of the two bones. The coracoacromial ligament runs from the coracoid process and the acromion. The coracoacromial ligament is a strong triangular band, extending between the coracoid process and the acromion. It is attached, by its apex, to the baksheesh of the acromion just in front of the articular surface for the clavicle; and by its long base to the whole distance of the lateral border of the coracoid process. This ligament, together with the coracoid process and the acromion, forms a restrict for the protection of the head of the humerus. The coracoclavicular ligament consists of 2 ligaments, the conoid...If you want to get a full essay, order it on our website: Orderessay
