9 Deltoid – arm abduction, flexion and extenson
Pectoralis major – adduction of arm, medial rotation of humerus Coracobrachialis – adduction of arm Pectoralis minor – stabilize scapula, draws scapula inferiorly

10 Serratus anterior – draws scapula forward and upward, abducts scapula
Triceps brachii – elbow extensor

11 Supraspinatus – synergist of deltoid
Infraspinatus – laterally rotates humerus Levator scapulae – elevages scapula and tilts glenoid cavity inferiorly Rhomboids – retracts scapula and rotates it to depress glenoid cavity

12 Teres major – adducts and medially rotates arm
Teres minor – laterally rotates arm Subscapularis – medial rotation and adduction of arm

13 Trapezius – elevates scapula, depresses scapula
Latissimus dorsi – adducts, extends and medially rotates the humerus

14 Biceps – elbow flexion, supination
Brachialis – PM of elbow flexion Brachioradialis – elbow flexion

15 Extensor carpi radialis longus – extends wrist and abducts hand
Extensor carpi ulnaris – extends wrist and adducts hand Extensor digitorum – extends wrist and fingers

16 Extensor pollicis longus and brevis – extends distal phalanx of thumb
Extensor digiti minimi – extends digit 5

17 Flexor carpii ulnaris – flexes and adducts hand at wrist
Flexor carpi radialis – flexes and abducts hand Flexor digitorum superficialis – flexes middle phalanges of digits 2 – 5 Flexor digitorum profundus – flexes distal phalanges of digits 2 - 5 Flexor pollicis longus – flexes thumb

18 Iliacus – hip flexion Psoas – hip flexion

19 Tensor fascia lata – stabilizes knee and hip, puts tension on fascia lata
Sartorius – flexes and laterally rotates hip, flexes knee Rectus femoris – knee extension Vastus group – extends knee

20 Pectineus – adduction Adductor brevis – thigh adductor and lateral rotation of thigh Adductor longus – as for brevis Adductor magnus –thigh adduction Gracilis – flexes knee, adducts the thigh, medial rotation of thigh

21 Gluteus maximus – hip extension, Lateral rotation of thigh, thigh abduction
Gluteus medius – thigh abduction, medial rotation of thigh (ant), lateral rotation of thigh (post) Gluteus minimus – abduction and medial rotation of hip

22 Biceps femoris – knee flexion, hip exension, rotates tibia laterally
Semimembranosis – knee flexion, hip extension, rotates tibia medially when knee is flexed Semitendinosis – same as semimembranosis

23 Tibialis anterior – dorsiflexion on foot, foot inversion
Peroneus longus – everts foot, plantarflexion of foot Extensor digitorum longus – extends digits 2 – 5 Extensor hallucis longus – extends toe and dorsiflexes foot

24 Gastrocnemius – plantar flexion of foot
Soleus – same Tibialis posterior – foot inversion, foot adduction

25 Flexor digitorum longus – flexes toes
Flexor hallucis longus – flexes great toe

26 Pronator teres – pronates and flexes forearm
Aconeus – synergist of triceps, abducts ulna during pronation
