intertubercular groove-lip

Pectoralis Major: Action

flexes the shoulder; adducts and medial rotates humerus

Pectoralis Minor

O: ribs 3-5


I: coracoid process of scapula


A: pull scapula forward and downward. fixed scapula: elevates ribs

Trapezius

O: superior nuchal line, external occipital protuberance, ligamentum nuchae, spinous processes of C7 and all thoracic vertebrae


I: lateral clavicle, acromion process and spine of scapula


A: adducts scapula, elevates and rotates shoulder upward, fixed scapula: draws the head backward

A: extends the shoulder, adducts and medially rotates humerus

Serratus Anterior

O: anterior superior surface of 1st eight or nine ribs


I: anterior surface of vertebral border of scapula


A: holds scapular to chest wall, rotates scapula so shoulder moves upward

Rhomboideus Major

O: Spinous processes of 2nd through 5th thoracic vertebrae


I: vertebral border of the scapula below base of the spine


A: adducts scapula, rotates the scapula so shoulder moves downward



Rhomboideus Minor

O: spinous process of C7 & T1 vertebrae


I: vertebral border of scapula at base of spine


A: adducts scapula, rotates the scapula so shoulder moves downward

Deltoid

O: lateral clavicle, acromion process and spine of scapula


I: deltoid tuberosity


A: flexes and extends shoulder; abducts humerus

Supraspinatus

O: supraspinous fossa


I: greater tubercle of the humerus- anterior aspect


A:abducts the humerus

Infraspinatus

O: infraspinatus fossa


I: greater tubercle of the humerus- posterior aspect


A: laterally rotates humerus

Subscapularis

O: subscapular fossa


I: lesser tubercle of humerus


A: adducts and medially rotates the humerus

teres minor

O: axillary border of scapula above teres major


I: lesser tubercle of humerus


A: laterally rotates humerus

teres major

O: inferior axillary border of scapula


I: intertubrecular groove- medial lip


A: extends the shoulder, adducts and medially rotates humerus

triceps

O: below the glenoid fossa (long head) and posterior shaft of the humerus (other two heads)


I: olecranon process of ulna
