Deltoideous parts (2) |
scapular, acromial |
|
|
Deltoideous |
Origin: the spine and acromial process of the scapula Insertion: deltoid tuberosity Action: flex the shoulder joint Innervation: axillary nerve |
|
|
Infraspinatus |
Origin: infraspinatus fossa Insertion:small circumscribed area on the lateral side of the greater tubercle of the humerus Action:prevent medial rotation when weight bearing and provide lateral stability to the shoulder joint Innervation:suprascapular nerve |
|
|
Teres minor |
Origin: infraglenoid tubercle and distal third of the caudal border of the scapula Insertion: teres minor tuberosity of the humerus Action: to flex shoulder joint, rotate the shoulder laterally and prevent medial roation when bearing weight Innervation: axillary nerve |
|
|
Supraspinatus |
Origin: supraspinous fossa Insertion: greater tubercle of the humerus, by a thick tendon Action: to extend and laterally stabilize the shoulder joint Innervation: suprascapular nerve |
|
|
Subscapularis |
Origin: subscapular fossa Insertion:the lesser tubercle of the humerus Action:to adduct, extend, and medially stabilize the shoulder joint. To rotate the shoulder medially and pervent lateral rotation when bearing weight Innervation:subscapular nerve |
|
|
Teres major |
Origin: caudal angle and adjacent caudal border of the scapula; caudal surface of the subscapularis Insertion: teres major tuberosity of the humerus Action: flex the shoulder, rotate the shoulder medially, and prevent lateral roation when weight bearing Innervation: axillary nerve |
|
|
Coracobrachialis |
Origin: coracoid process of the scapula Insertion: crest of the lesser rubercle of the humerus proximal to the teres major tuberosity Action: adduct, extend, and stabilize the shoulder joint Innervation: musculocutaneous nerve |
