1. APPENDICULAR SKELETON

2. Pectoral/Shoulder Girdles Consists of the clavicle and scapula The pectoral girdles and their associated muscles = your shoulders Attach the upper limbs to the axial skeleton Are light and allow the upper limbs to have a degree of mobility not seen anywhere else in the body

3. Lots of mobility because… 1.Only the clavicle attaches to the axial skeleton (scapula can move freely allowing the arm to move with it) 2.Socket of the shoulder joint is shallow and not very reinforced --- good for flexibility but poor for support (shoulder dislocations are common)

5. Clavicles (collarbones) - provides attachment points and act as a brace (holding the arms out laterally), not strong Scapulae (shoulder blades) The Shoulders

6. The Arms Humerus (upper arm) Ulna (lower arm/forearm) Radius (lower arm/forearm)

7. HANDS Phalanges (digits) Metacarpals (palm) Carpals (wrists)

8. The Pelvic (Hip) Girdle Attaches the lower limbs to the axial skeleton Transmits the weight of the upper body to the lower limbs Secured to the axial skeleton by some of the strongest ligaments in the body (not as much flexibility as shoulder girldle but more stability)

9. Hip Girdle Hipbone (coxal bone) Sacrum Coccyx Sacroiliac Joint Interpubic Joint

10. The Leg Femur (thigh bone) - largest, longest, and strongest bone of the body Patella (knee) Tibia (Shin bone) Fibula

11. Divided into three regions: the ilium, ischium, and pubis - separate as a child, fuse in adults The male pelvis is heart-shaped and narrow The female pelvis is much wider and flatter, with a larger central cavity

12. The Foot Tarsals (ankle) Metatarsals (instep) Phalanges (digits/toes)
