3. Axial Skeleton Skull 22 bones – 8 cranial bones – 14 facial bones Middle ear bones6 bones Hyoid1 bone Vertebral Column26 bones – 7 cervical vertebrae – 12 thoracic vertebrae – 5 lumbar vertebrae – 1 sacrum – 1 coccyx Thoracic Cage – 24 ribs 25 bones – 1 sternum Table 7.3 Total = 80 axial bones

4. Appendicular Skeleton Pectoral Girdle Upper Limbs Pelvic Girdle Lower Limbs Total = 126 appendicular bones

5. The Pectoral Girdle Composed of 4 parts – 2 scapulae (shoulder blades) – 2 clavicles (collar bones) Does not form a closed ring Supports the upper limbs Attaches some of the muscles that move the upper limbs

6. Articulation = Joint The junction of two or more bones Proximal = closer to core of body Distal = further from core of body
