1. Appendicular Skeleton Bones of the limbs and supporting elements Approx. 126 bones

3. Pectoral Girdle “shoulder” Clavicles and scapulae Clavicle articulates with the manubrium of the sternum Only direct connection to the axial skeleton Humerous articluated with the scapula at the glenoid cavity

5. Upper Limbs Brachium (arm) contains the humerus Deltoid tuberosity- rough elevation formed from attachment of deltiod muscle Antebrachium (forearm)- contains the radius and ulna “in anatomical position the ulna is medial” Carpals form wrist, metacarpals are the bones in the hand, and the phalanges from the fingers

7. Pelvic Girdle More massive 2 fused os coxae (hip bones)- made of the ilium, ischium, and pubis Attach together by a pad of fibrocartilage called the pubic symphysis Articulates with the sacrum Socket for connection with the femur

9. Pelvis 2 hip bones, sacrum, and coccyx Females vs. male pelvis Enlarged outlet, less curve of sacrum, broader, greater pubic angle, lighter, and smoother

11. Lower Limbs Femur- longest, heaviest bone in the body Patella- large sesmoid bone that forms within the the tendon of the quads Tibia- large medial bone of the lower leg, transfer weight from femur to the ankle Fibula- outer bone, doesn’t support weight, provides lateral stability to the ankle

12. Ankle/ Foot 7 Tarsal bones form the ankle Talus tranfers weight to the foot from the tibia Calcaneus- heel, attachment site for achilles tendon tranfers weight from the talus to the ground Metatarsals- foot bones Phalanges- toe bones

13. Individual Variation Skeletons reveal: an individual’s musculature, medical history, gender, age, and nutrition.
