THE HUMAN SKELETAL SYSTEM The bones are the framework that provides structure throughout the body and walking facilitates. The human skeletal is composed of 206 bones and 32 teeth. The skeletal system includes Cartilage and ligament. The cartilage is soft, gel-like padding between the bones that protect the joints and facilitates movement while the ligament is a rigid muscle group that connects bone to bone and provides joint elasticity. Types of bones there are 5 types of bone that create the skeleton 1. Long bone (generate RBC, support weight and facilitate movement) 2. Flat bone(flat bones protect internal organs) 3. Sesamoid bone(protect tendons provide) 4. Short bones(stability and movement) 5. Irregular shaped bones(protect organs in the pelvic cavity)
