Learning objectives
Learning Objectives

  • Identify the functions of the skeleton.

  • Explain the role that joints play in the body.


Functions of the skeletal system
Functions of the Skeletal System

  • Your skeleton has five major functions.


Functions of the skeletal system1
Functions of the Skeletal System

  • 1.

  • a. It provides shape and support


Functions of the skeletal system2
Functions of the Skeletal System

  • 1.

  • a. It provides shape and support

  • b. enables you to move


Functions of the skeletal system3
Functions of the Skeletal System

  • 1.

  • c. protects your organs


Functions of the skeletal system4
Functions of the Skeletal System

  • 1.

  • c. protects your organs

  • d. produces blood cells


Functions of the skeletal system5
Functions of the Skeletal System

  • 1.

  • e. stores minerals


Functions of the skeletal system6
Functions of the Skeletal System

  • Your skeleton determines the shape of your body.


Functions of the skeletal system7
Functions of the Skeletal System

  • Your skeleton determines the shape of your body.

  • 2. The backbone, also called the vertebral or spinal column, is the center of the skeleton.


Functions of the skeletal system8
Functions of the Skeletal System

  • 3.

  • The 26 small bones that make up the backbone are the vertebrae.


Functions of the skeletal system9
Functions of the Skeletal System

  • Your skeleton allows you to move. Most of the body’s bones are associated with muscles.


Functions of the skeletal system10
Functions of the Skeletal System

  • Your skeleton allows you to move. Most of the body’s bones are associated with muscles.

  • 4. The muscles pull on the bones to make the body move.


Functions of the skeletal system11
Functions of the Skeletal System

  • Bones also protect many of the organs in your body.


Functions of the skeletal system12
Functions of the Skeletal System

  • Bones also protect many of the organs in your body.

  • 5. Your skull protects your brain, your ribs form a protective cage around your heart and lungs.


Functions of the skeletal system13
Functions of the Skeletal System

  • Some of your bones produce substances that your body needs.


Functions of the skeletal system14
Functions of the Skeletal System

  • Some of your bones produce substances that your body needs.

  • 6. For example, the long bones of the arms and legs make certain blood cells.


Joints of the skeleton
Joints of the Skeleton

  • 7. A joint is a place in the body where two bones come together. Joints allow bones to move in different ways.


Joints of the skeleton1
Joints of the Skeleton

  • 7. A joint is a place in the body where two bones come together. Joints allow bones to move in different ways.

  • 8. There are two kinds of joints – immovable and movable.


Joints of the skeleton2
Joints of the Skeleton

  • Some joints in the body connect bones in a way that allows little or no movement. These joints are called immovable joints.


Joints of the skeleton3
Joints of the Skeleton

  • Some joints in the body connect bones in a way that allows little or no movement. These joints are called immovable joints.

  • 9. The bones of the skull are held together by immovable joints.


Joints of the skeleton4
Joints of the Skeleton

  • 10. These are the movable joints that we have in our bodies.

Kind of Motion: Forward or backward

Where in the Body: Knees and elbows


Joints of the skeleton5
Joints of the Skeleton

  • 10. These are the movable joints that we have in our bodies.

Kind of Motion: Swing freely in a circle

Where in the Body: Hips and shoulders


Joints of the skeleton6
Joints of the Skeleton

  • 10. These are the movable joints that we have in our bodies.

Kind of Motion: Rotation

Where in the Body: Neck


Joints of the skeleton7
Joints of the Skeleton

  • 10. These are the movable joints that we have in our bodies.

Sliding Joint

Kind of Motion: One bone slides over another

Where in the Body: Wrists and ankles


Joints of the skeleton8
Joints of the Skeleton

  • 11. The bones of the in movable joints are held together by strong connective tissues called ligaments.
