Introduction to the Skeletal System

• The skeletal system provides support, protection, and movement for the body.

• It is made up of bones, cartilage, ligaments, and tendons.

• The skeletal system is divided into axial skeleton (skull, vertebral column, and rib cage) and appendicular skeleton (limbs and girdles).

• Functions include hematopoiesis (blood cell production) and storage of minerals.

Types of Bones

• Long Bones: longer than they are wide, found in arms and legs

• Short Bones: cube-shaped, found in wrists and ankles

• Flat Bones: thin and curved, protect organs like skull and ribs

• Irregular Bones: unique shape, found in spine and face

Understanding Joints

• Joints are the points where two or more bones meet.

• They allow for movement and flexibility in the skeletal system.

• There are different types of joints including hinge, ball-and-socket, and pivot joints.

• Each type of joint has its own range of motion and function.

Functions of the Skeletal System

• Support: Provides structural support for the body

• Protection: Protects vital organs like the brain and heart

• Movement: Serves as attachment points for muscles, allowing movement

• Storage: Stores minerals like calcium and phosphorus

• Blood Cell Production: Produces red and white blood cells in the bone marrow
