Skeletal System
Functions of the Skeletal System 1. SUPPORT – it supports the softer
tissues and provides points of attachment for most skeletal muscles.
2. PROTECTION – bones protect internal organs from injury (skull protects brain)
3. MOVEMENT – muscles attach to bones, and allow the body to move at joints when the muscles contract
Functions of the Skeletal System
4. PRODUCTION OF BLOOD – blood cells are produced in bone marrow in larger bones
5. STORAGE – minerals (Calcium and Phosphorus) stored in bones and can be released into the blood to keep proper a balance
Parts of the Bone
Cartilage : Found on the ends of bones, it is slippery and flexible to protect bones at joints.
Parts of the Bone
Hard bone: strong material found on the outside of bone. Provides great strength.
Periosteum: thin membrane covering the outside of bones
Parts of the Bone
Spongy Bone: located on the ends of bones, made of many open spaces, makes bones lightweight and strong
Parts of Bone
Marrow: found in the center of bones, makes new blood cells
