- Skull
- Bones assoc. w/ skull: hyoid+auditory ossicles
- Vertebral column
- Thoracic cage (ribs+sternum)
Appendicular skeleton
- Pectoral (shoulder) girdle
- Upper extremity
- Pelvic girdle
- Lower extremity

Sacral & Coccygeal
Each 1 bone but have regions
S1-5 &. Co1-Co3
Skull associated bones
Hyoid
Auditory ossicles

Thoracic cage function
Protective barrier around some vital organs
- lungs, heart + major blood vessels
