|
What do the rotator cuff muscles do? |
Hold the head of the humerus into the glenoid cavity |
|
|
Scapular movements increase the _________ |
range of motion of the humerus |
|
|
Muscles that move the pectoral girdle... |

|
Pectoralis minor |
Anterior Origin: Ribs 3-5 Insertion: Coracoid process of scapula Draws scapula laterally Protraction |
|
|
Serratus anterior |
Anterior Origin: all ribs Insertion: medial border of scapula Draws scapula laterally and forward Reaching and pushing |
|
|
Trapezius |
Posterior Origin: nuchal lines, thoracic spinous processes Insertion: superior edge of spine and acromion of scapula, lateral clavicle Lateral rotation, elevation, depression, retraction |
|
|
Levator scapulae |
Posterior Origin: tranverse process of c1-c4 Insertion: superior angle and medial border of scapula Elevates scapula, Flexes neck laterally |
|
|
Rhomboid major |
Posterior Origin: spinous process of t2-t5 Insertion: medial border of scapula Retracts scapula and braces shoulder |
|
|
Rhomboid minor |
Posterior Origin: spinous process c7 - t1 Insertion: Medial border of scapula (near scapula spine) Retracts scapula and braces border |
|
|
Pectoralis major |
Origin: Sternum and medial clavicle Insertion: proximal humerus Flexes, adducts, and medially rotates humerus |
|
|
Latisimus dorsi |
Origin: spinous process of T8-L5 and superior sacrum (some people all have origin on inferior angle of scapula) Insertion: prximal humerus Adducts and medially rotates humerus |
|
|
Deltoid |
Origin: Lateral clavicle, inferior edge of spine and acromion of scapula Insertion: lateral, middle of humerus Rotates and abducts arm |
|
|
Teres major |
Origin: posterior inferior angle of scapula Insertion: medial, proximal humerus Extenion and medial rotation of humerus |
|
|
coracobrachialis |
Origin: coracoid process of scapula Insertion: middle, medial humerus flexes and medially rotates humerus |
