  1. Skeletal and MuscularSystem

  2. Skeletal System • Interacts with muscular system for movement of the body • Coordinated by nervous system

  3. What is Cartilage? • Cartilage is connective tissue that is more flexible than bone • Cushions bones

  4. Cartilage

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

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

  7. Vertebrae • The 26 small bones that make up the backbone

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

  9. What are the two kinds of joints in the body? • The two kinds of joints in the body are immovable and movable joints

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

  11. Immovable Joint

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

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

  14. Ligaments

  15. Tendons • Attach muscles to bones

  16. Marrow • The spaces in bone that contain a soft connective tissue is called MARROW

  17. Bone Marrow

  18. Muscles • Motion of organs • Locomotion of Body • Interacts with all organ systems causing movement of tissues and organs

  19. Muscular System

  20. 3 Types of Muscles

  21. Skeletal Muscles • Type of striatedmuscle, attached to the skeleton. • Facilitate movement, by applying force to bones and joints; via contraction. • Contract voluntarily, although they can contract involuntarily.

  22. Skeletal Muscle

  23. Cardiac Muscle • Type of striatedmuscle found within the heart. • Function is to "pump" blood through the circulatory system by contracting

  24. Cardiac Muscle

  25. Smooth Muscle • Type of non-striatedmuscle, found in organs blood vessels, the bladder, the uterus, and the digestive system

  26. Smooth Muscle

  27. Arthritis • Painful Inflammation of freely movable joints. • Immune system attacks tissues around joints • Symptom stiffening & swelling

  28. Gout • Systemic disease (throughout body) • Build up of uric acid • Settles in joints causing inflammation and swelling

  29. Tendonitis • Inflammation in the tendons

  30. Osteoporosis • A condition in which the body’s bones become weak and break easily
