Study Notes
The Skeletal System
- Provides structural support and shape for the body
- Allows the body to move
- Protects internal organs: heart, lungs, brain
Structure of the Skeletal System
- 206 bones in the adult body
- Babies have approximately 305 bones that fuse together as they grow.
Functions of the Skeleton
- Provides support and shape for the body
- Allows movement
- Protects internal organs
- Produces red blood cells and platelets in the bone marrow
- Stores minerals like calcium and phosphorus
Axial Skeleton
- Protects delicate organs
- Includes the skull, vertebral column, ribs, and sternum
Appendicular Skeleton
- Provides support and aids in movement
- Includes bones of shoulders, arms, hips, legs, and feet
The Skull
- Consists of the cranium and facial bones
- Made up of eight bones joined together
- Protects the brain
- The eye socket protects the eye
- The mandible (jawbone) protects the teeth
