12. Appendicular muscles to know origin and insertion Biceps brachii- Rectus femoris Triceps brachii- Biceps femoris Sartorius- Deltoid - Gastrocnemeus

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

20. Structures to know and identify Tendons Galea aponeurosis Linea alba Iliotibial tract Calcaneal “achiles” tendon
