The Skeletal System Understanding the Human Skeleton Overview of the Skeletal System The skeletal system provides structure and support for the body. It is made up of bones, joints, and cartilage.  1. Support: Provides structure to the body. Functions 2. Protection: Protects vital organs (e.g., skull protects the brain). of the Skeletal 3. Movement: Works with muscles to help us move. System 4. Production of Blood Cells: Bone marrow produces red and white blood cells. 5. Storage of Minerals: Stores calcium and phosphorus, which are essential for body functions.  1. Bones: Provide structure, protect organs, and store calcium. Parts of the 2. Joints: Area where 2 bones Skeletal meet and work together which System allows movement by connecting bones. 3. Cartilage: It is a firm tissue but is softer and much more flexible than bone that supports bones and protects them where they rub against  Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements. Pivot joints, such as the neck joints, allow limited rotating movements. Hinge joints, such as in the fingers, knees, elbows, and toes, allow only bending and straightening movements.  1. An adult human body has 206 bones. 2. Babies are born with about 270 bones, some of which fuse together as they grow. Interesting 3. The femur (thigh bone) is Facts the longest bone in the body. 4. The stapes is the body's smallest bone! Sometimes called the stirrup, this delicate bone works with two others in the ear to send sound Skeletal System Charades Instructions: 1. Divide the class into two teams. 2. Assign each team a set of skeletal system terms to act out (e.g., bones, joints, cartilage). 3. One student from each team will come to the front and silently act out the term given to them while their team tries to guess the term. 4. The team that guesses the most terms correctly wins the round. 5. Rotate students for multiple rounds until all terms have been covered.  The skeletal system plays a critical role in protecting our organs, supporting movement, and Conclusion producing blood cells, and storing essential minerals. Taking care of our bones is essential for a healthy life.
