Objective 1
Identify the subdivisions of the skeleton as axial or appendicular
Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings
The Skeletal System Parts of the skeletal system
Bones (skeleton)
Joints – point of movement
Cartilages – protection
Ligaments – connect bone to bone
Divided into two divisions
1. Axial skeleton
2. Appendicular skeleton
Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings
The Axial Skeleton Forms the longitudinal, central part of the
body
Divided into three parts
1. Skull

The Axial Skeleton Forms the longitudinal, central part of the
body
Divided into three parts
1. Skull
2. Vertebral column
Copyright © 2006 Pearson Education, Inc., publishing as Benjamin Cummings
The Vertebral Column Vertebrae separated
by intervertebral discs
The spine has a normal curvature
Each vertebrae is given a name according to its location

The Bony Thorax Forms a cage
to protect major organs
Made-up of three parts
Sternum
Ribs
Thoracic vertebrae
