Medical Assistant Prep / Unit 3 MAS 056 short lesson, about 20 seconds
Two Divisions of the Skeleton
Captions available
The idea
The skeleton has two divisions: the axial skeleton along the body's center and the appendicular skeleton of the limbs.
In practice
The axial skeleton, about eighty bones, includes the skull, spine and ribs; the appendicular skeleton, about one hundred twenty-six bones, includes the limbs and the girdles that attach them.
Where people slip
The shoulder and pelvic girdles belong to the appendicular skeleton, not the axial.
