Origin: occipital bone, ligamentum nuchae & spinous processes of thoracic vertebrae
Insertion: clavicle and scapula (acromion and scapular spine) Action: elevate, retract, depress, or rotate scapula upward and/or elevate clavicle; extend neck |
Trapezius
|
|
Origin: spinous process of vertebrae C7-T1
Insertion: vertebral border of scapula Action: adducts & performs downward rotation of scapula |
Rhomboideus Minor
|
|
Origin: spinous process of superior thoracic vertebrae
Insertion: vertebral border of scapula from spine to inferior angle Action: adducts and downward rotation of scapula |
Rhomboideus Major
|
|
Origin: transverse precesses of C1-C4 vertebrae
Insertion: vertebral border of scapula near superior angle Action: elevates scapula |
Levator Scapulae
|
|
Origin: anterior and superior margins of ribs 1-8 or 1-9
Insertion: anterior surface of vertebral border of scapula Action: protracts shoulder: rotates scapula so glenoid cavity moves upward rotation |
Serratus Anterior
|
|
Origin: anterior surfaces and superior margins of ribs 3-5
Insertion: coracoid process of scapula Action: depresses & protracts shoulder, rotates scapula (glenoid cavity rotates downward), elevates ribs |
Pectoralis Minor
|
|
Origin: supraspinous fossa of scapula
Insertion: greater tuberacle of humerus Action: abduction at the shoulder |
Supraspinatus
|
|
Origin: infraspinous fossa of scapula
Insertion: greater tubercle of humerus Action: lateral rotation at shoulder |
Infraspinatus
|
|
Origin: clavicle and scapula (acromion and adjacent scapular spine)
Insertion: deltoid tuberosity of humerus Action: abducts shoulder, flexion and extension, medial and lateral rotation of humerus |
Deltoid
|
|
Origin: lateral border of scapula
Insertion: greater tubercle of humerus Action: lateral rotation at shoulder |
Teres Minor
|
|
Origin: inferior angle of scapula
Insertion: medial lip of intertubercular groove of humerus Action: extension, adduction & medial rotation at shoulder |
Teres Major
|
|
Origin: subscapular fossa of scapula
Insertion: lesser tubercle of humerus Action: medial rotation at shoulder |
Subscapularis
|
|
Origin: cartilages of ribs 2-6, gladiolus & inferior, medial portion of clavicle
Insertion: crest of greater tubercle & lateral lip of intertubercular groove of humerus Action: flexion, adduction & medial rotation at shoulder |
Pectoralis Major
|
|
Origin: spinous process of inferior T and all L vertebrae, ribs 8-12, and lumbodorsal fascia
Insertion: floor of intertubercular groove of the humerus Action: extension, adduction, and medial rotation at shoulder |
Latissimus Dorsi
|
|
Origin: coracoid process
Insertion: medial margin of shaft of humerus Action: adduction and flexion at shoulder |
Coracobrachialis

Triceps Brachii (lateral head, long head, medial head)
|
|
Origin: anterior, distal surface of humerus
Insertion: ulnar tuberosity Action: flexion at elbow |
Brachialis
|
|
Origin: ridge superior to lateral epicondyle of humerus
Insertion: lateral aspect of styloid process of radius Action: flexion at elbow |
Brachioradialis
|
|
Origin: medial epicondyle of humerus & coronoid process of ulna
