| Muscle | Origin | Insertion | Action |
| Sternocleidomastoid | manubrium and medial Clavicle | Mastoid Process, superior nuchal line | rotates,extends and flexes neck |
| biceps brachii | short head: coracoid process of scapulalong head: supraglenoid tubercle | tuberosity of the radius | flexion of elbow, supination of forearm.long head: flexion of humerus |
| Scalenes | Transverse process of cervical vertebrae | Ribs 1 and 2 | Flexes and rotates neck, elevates ribs 1&2 |
| Triceps Brachii | Inferior,distal margin of mandible(anterior belly)mastoid notch of long head:infraglenoid tuberclelateral head:posterior surface proximal half of humerus.medial head:posterior surface distal half of humerus. | olecranon process of ulna | extension of elbow.long head: extension of humerus |
| Deltoid | lateral 1/3 of clavicle, lateral acromion and spine of scapula | deltoid tuberosity of humerus | anterior:flexion, horizontal adduction, medial rotation of humerus.middle:abduction of humerus to 90 degrees.posterior-extension, horizontal abduction, lateral rotation of humerus. |
| Pectoralis Major | medial half of clavicle, sternum and cartilages of upper 6 ribs. | greater tubercle of humerus. | all fibers: adduct and medially rotate g/h joint. assist in elevating thorax during forced inhalation.upper fibers:flex and horizontally adduct g/h joint.lower fibers: extend g/h joint |
| Latissimus Dorsi | spinous processes of last six thoracic vertebrae, last 3-4 ribs, thoracolumbaraponeurosis and posterior iliac crest. | crest of lesser tubercle of humerus | extension, medial rotation and adduction of g/h joint. |
| Supraspinatus | supraspinous fossa of scapula | greater tubercle of humerus | abduction of g/h joint.stabilizes head of humerus |
| Infraspinatus | infraspinous fossa of scapula | greater tubercle of humerus | lateral rotation, adduction, extension and horizontal abduction of g/h joint.stabilizes head of humerus. |
| Teres Minor | superior half of lateral border of scapula | greater tubercle of humerus | laterally rotates, adducts, extends and horizontally abducts g/h joint.stabilizes head of humerus. |
| Subscapularis | subscapular fossa of scapula | lesser tubercle of humerus | medially rotates g/h joint.stabilizes head of humerus. |
| Levator Scapula | Transverse processes first thru fourth cervicle vertebrae. | upper region of medial border and superior angle of scapula. | elevation and downward rotation of scapula.laterally flexes head and neck.rotates head and neck to same side. |
| Trapezius | ext. occipital protuberance, med. portion superior nuchal line, ligamentum nuchae and spinous processes C-7 thru T-12 | lateral 1/3 clavicle, acromion and spine of scapula. | upper fibers:bilat- ext. head & neckunilat- lat. flex head & neck same side, rot. head & neck opp. side, elevate scap, upwardly rot. scap.middle fibers:abduct scap, stabilize scap.lower fibers:depress scap, upwardly rotate scap |
| Rhomboids | maj-spinous processes T-2 to T-5min- spinous processes C-7 &T-1 | maj- med. border of scap from spine of scap to inferior angle.min- upper portion medial border of scap across from spine. | adduct, elevate and downwardly rotate scapwnwardly rotate scap. |
| Pectoralis Minor | 3rd, 4th and 5th ribs | coracoid process of scapula | depresses scap, abducts scapula, tilts scapula anteriorly and assists in forced inhalation. |
| Serratus Anterior | surfaces of upper 8 or 9 ribs | anterior surface of medial border of scapula | abducts scap, depresses scap, holds medial border of scap against ribcage. |
| Quadriceps(Rectus Femoris) | anterior inferior iliac spine (AIIS) | tibial tuberosity | extends the knee, flexes the hip |
| Quadriceps(Vastus Group) | lateralis-lat. lip linea aspera &gluteal tuberositymedialis-medial lip linea asperaintermedius-anterior and lateral shaft of femur | all - tibial tuberosity | all - extend the knee |
| Hamstrings(Biceps Femoris) | long head-ischial tuberosityshort head- lateral lip of linea aspera | head of fibula | flex knee, lat. rotate flexed knee, extend hip, lat. rotate hip, tilt pelvis posteriorly |
| Hamstrings(Semimembranosus and Semitendinosus) | ischial tuberosity | semimem- post aspect of medial condyle of tibiasemiten- prox. medial shaft of tibia and pes anserinus tendon | both- flex knee, medially rotate flexed knee, extend hip medially rotate hip, tilt pelvis posteriorly. |
| Gastrocnemius | condyles of the femur (posterior surfaces) | calcaneus via calcaneal tendon | flex knee, plantar flex ankle |
| Soleus | soleal line, posterior surface of tibia and proximal, posterior surface of fibula. | calcanues via calcaneal tendon | plantarflexion of the ankle |
| Piriformis | anterior surface of sacrum | greater trochanter | laterally rotates hip, abducts thigh when hip is flexed. |
