13. Biceps brachii Origin: SH coracoid process; LH supraglenoid tubercle
Insertion: Radial tuberosity
Action: flex elbow and shoulder

14. Triceps brachii
Origin: Lat H: Sup, lateral margin of humerus; LH: Infraglenoid tubercle; Med H: Post humerus
Insertion: Olecranon of ulna
Action: Extension at elbow

15. Deltoid Origin: Clavicle, scapula acromion and spine
Insertion: Deltoid tuberosity of humerus
Action: Abducts shoulder; flexion and rotation of humerus; extension and lateral rotation of humerus

16. Rectus femoris (Quads)
Origin: Ant iliac spine and sup. margin acetabulum
Insertion: Patella and tibial tuberosity
Action: Extension of leg at knee; flex thigh at hip

17. Sartorius Origin: Ant, superior spine of ilium
Insertion: Medial aspect tibial tuberosity
Action: Flexes, abducts and laterally rotates thigh at hip; flexes knee

18. Biceps femoris (Hamstrings)
Origin: LH: ischial tuberosity; SH: linea aspera of femur
Insertion: Head of fibula
Action: Flexes knee; extends hip; laterally rotates leg

19. Gastrocnemius Origin: Lateral condyle and popliteal surface of femur
Insertion: Calcaneus via achilles tendon
Action: Flexes knee and plantar flexion of foot
