Skeleton System Terms

Front 1

Axial Skeleton

Back 1

Bones of the skull, vertebral column, and thoracic cage.

-This part of the skeleton forms the 1. longitudinal axis of the body
2.supports the head, neck and trunk, and
3. protects the brain, spinal cord, and the organs in the thorax

Front 2

Skull

Back 2

Formed by 22 cranial and facial bones

1.Form the framework of the face

2.contain cavities for the special sense organs of sight, taste, and smell

3. provide openings for air and food passage

4.secure the teeth

5.anchor the facial muscles of expression, which we use to show our feelings.
