4 What is Cartilage? Cartilage is connective tissue that is more flexible than bone Cartilage is connective tissue that is more flexible than bone Cushions bones Cushions bones

5 Cartilage

6 Bones 1. Supports body 1. Supports body 2. Protects Organs 2. Protects Organs 3. Produce new red blood cells in the bone marrow 3. Produce new red blood cells in the bone marrow

7 Bones 4. Enables you to move 4. Enables you to move 5. Stores certain materials until your body needs them. 5. Stores certain materials until your body needs them.

10 What is a Joint? A joint is the place where two bones come together A joint is the place where two bones come together Joints help the skeleton move the body. Joints help the skeleton move the body.

11 What are the two kinds of joints in the body? The two kinds of joints in the body are immovable and movable joints The two kinds of joints in the body are immovable and movable joints

12 What are the two main immovable joints in our bodies? Bones of the skull Bones of the skull Joints that attach the ribs to the sternum Joints that attach the ribs to the sternum

13 Immovable Joint

14 Joint Kind of Motion Where It’s Found in the Body Hinge Forward or backward motion KneeElbow Ball-&- Socket Greatest range of motion Shoulder Blade Hips Pivot One bone to rotate around another Neck Gliding One bone to slide over another WristAnkles

15 When do bone cells form new bone tissue? New bone tissue forms to fill the gap between the broken ends of the bone. New bone tissue forms to fill the gap between the broken ends of the bone.

16 Ligaments The bones in movable joints are held together by strong connective tissues is called LIGAMENTS The bones in movable joints are held together by strong connective tissues is called LIGAMENTS Connect bone to bone Connect bone to bone

17 Ligaments

18 Tendons Attach muscles to bones Attach muscles to bones

19 Marrow The spaces in bone that contain a soft connective tissue is called MARROW The spaces in bone that contain a soft connective tissue is called MARROW

20 Bone Marrow

21 Muscles Motion of organs Motion of organs Locomotion of Body Locomotion of Body Interacts with all organ systems causing movement of tissues and organs Interacts with all organ systems causing movement of tissues and organs
