| Sternocleidomastoid | manubrium of sternum, sternal end of clavicle - mastoid process - flex head forward and downward onto chest |
| Pectoralis Major | clavicle, sternum, costal cartilages, aponeurosis of ext oblique - groove between greater and lesser tubercles of humerus - flex humerus |
| Deltoid | lateral third of clavicle, acromion and spine of scapula - deltoid tuberosity of humerus - abduct humerus |
| Internal Intercostalis | expiration (lower ribs) |
| External Intercostalios | inspiration (raise ribs) |
| Latissimus Dorsi | broad aponeurosis attached to thoracic and lumbar vertebrae, spine of sacrum, iliac crest, lower ribs - groove between greater and lesser tubercles of humerus - draw shoulder downward and backward |
| Supraspinatus | supraspinatus fossa of scapula - greater tubercle of humerus - abducts humerus |
| Infraspinatus | rotate humerus laterally |
| Teres Major | rotate humerus medially |
| Subscapularis | rotate humerus medially |
| External Oblique Internal Oblique Rectus Abdominus | keep abdominal organs compressed |
| Biceps Brachii | medial tendon attached to coracoid process, lateral tendon fits into groove between greater and lesser tubercles of humerus - radial tuberosity of radius - flex forearm |
| Brachialis | lower half of humerus - front surface of coronoid process of ulna - flex forearm |
| Brachioradialis | above lateral epicondyle of humerus - lateral surface of radius above styloid process - flex forearm |
| Triceps Brachii | long head - scapula, lateral head - posterior surface of humerus, medial head - surface below radial groove oleocranon process of ulna extend forearm |
| Flexor Carpi Radialis | medial epicondyle of humerus - procimal portion of 2nd and 3rd metacarpals - abduct hand |
| Flexor Carpi Ulnaris | medial epicondyle of humerus, olecranon process of ulna - tendon that attach to base of 3rd metacarpal - adduct hand |
| Flexor Digitorium Superficialis | humerus, ulna, radius - tendons atached to middle phalanges of 2-5 fingers - flex fingers |
| Palmaris Longus | tenses palmar fascia |
| Extensor Carpi Radialis Longus, Brevis | humerus - extension of wrist and hand |
| Extensor Digitorium | lateral epicondyle of humerus - extend fingers |
| Gluteus Maximus | ilium, sacrum, coccyx - iliotibial tract, posterior part of the femur - rotate femur |
| Gluteus Minimus | ilium - lateral part of great trochanter - medially rotate femur |
| Biceps Femoris | tendon from anterior inferior iliac spine and from groove above acetabulum - common tendon iinserting into tibia - flex thigh |
| Vastus Lateralis | lateral lip of linea asper- common tendon inserting into tibia - flex thigh |
| Vastus Medialis | linea aspera - common tendon iinserting into tibia - flex thigh |
| Vastus Intermedius | front and lateral suface of femur - common tendon iinserting into tibia - flex thigh |
| Sartorius | anterior, superior spine of ileum - medial surface of tibia - rotate leg laterally |
| Tensor Fascia Latae | anterior outer lip of iliac crest, anterior superiod spine, deep surface of fascia latae - between 2 surfaces of iliotibial tract - flex thigh |
| Gracilis | flex thigh |
| Gastrocnemius | posterior surface of medial and lateral condyles of femur - tendon of Achilles that insert on calcaneous of foor - plantar flexion |
