Proximal Phalanges

Right Deltoid


- Origin: clavicle, acromion and spine of scapula


- Insertion: deltoid tuberosity of humerus


- Action: arm abduction (can aid in flexion, extension, and rotation of humerus)

Left Triceps brachii


- Origin: glenoid cavity, posterior humerus, and distal radial groove on posterior humerus


- Insertion: Olecranon process of ulna


- Action: Powerful forearm extensor; antagonist of forearm flexors (brachialis and biceps brachii)

Left Pectoralis major


- Origin: clavicle, sternum, and (cartilage of) ribs 1-6


- Insertion: Intertubercular sulcus of humerus


- Action: Prime mover of arm flexion; adduction, medially rotates arm; pulls chest upward (forced inspiration)

Right Infraspinatus


- Origin: Infraspinous fossa of scapula


- Induction: Greater tubercle of humerus


- Action: Lateral rotation of humerus; helps hold head of humerus in the glenoid cavity; stabilizes shoulder

Right Latissimus dorsi


- Origin: Spinous processes of lower six thoracic vertebrae, lumbar vertebrae, last three to four ribs, and iliac crest


- Induction: Intertubercular sulcus of humerus


- Action: Prime mover of arm extension; adducts and medially rotates arm; depresses scapula; brings arm down in power stroke

Left Trapezius


- Origin: occipital bone, spines of C7 and all thoracic vertebrae


- Induction: Acromion and spinous process of scapula, lateral third of clavicle


- Action: Extends head; raises, rotates, and retracts scapula (shrugging)

Right Pectoralis minor


- Origin: Anterior surface of ribs 3-5 (near costal cartilages)


- Induction: Coracoid process of scapula


- Action: Draws scapula forward and inferiorly (or with scapula fixed, draws chest superiorly)

Right Serratus anterior


- Origin: Lateral aspect of ribs 1-8


- Induction: Vertebral border of anterior surface of scapula


- Action: Move scapula forward towards chest wall; abduction and raising of arm

Right Levator scapulae


- Action: elevates and adducts scapula; flexes neck to the same side

Right Major and Minor Rhomboids


- Origin: Spinous process of C7 and T1-T5


- Induction: Medial border of scapula


- Action: Pulls scapula medially; stabilizes scapula; rotates glenoid cavity downward;

Coracobrachialis

Teres major

Teres minor

Supraspinatus

Subscapularis

Right Biceps brachii


- Origin: coracoid process (tendon runs in intertubercular sulcus and capsule of shoulder joint)


- Insertion: Radial tuberosity


- Action: Flexion of elbow and supination of forearm. "It turns the corkscrew and pulls the cork"

Brachioradialis


- Origin: Lateral ridge at distal end of humerus


- Insertion: Base of styloid process of radius


- Action: Synergist in forearm flexion
