SSHS Human Anatomy & Physiology Structure, Support and Movement Unit Topic 3
Structure, Support and Movement
Skeletal System
Topical Understanding
The skeletal system supports the body, protects internal organs, provides for movement, stores mineral reserves, and provides a site for blood cell formation. Skeletal bones are a solid network of living cells and protein fibers that are surrounded by deposits of calcium salts. Joints allow movement of the skeleton and can be classified by their structure and type of movement provided. Damage and disease of the bones and skeleton can impact the overall health of an individual.
Essential Questions
· How does the skeletal system depend upon all other body systems? How do other body systems depend upon the skeletal system?
· How does the structure of bone relate to its function?
· How do bones grow?
· How are the bones of the skeleton classified and organized?
· How do joints allow for different types of movement?
· How does the skeleton stay together?
