  1. Skeletal System How do the bones of the skeletal system work?

  2. Skeletal System Activating Strategy: Think/Pair Share p.18 What is a joint? How do the bones of the skeletal system work?

  3. Skeletal System Preview Vocabulary: Articulation Synovial Pivot Ball-and-Socket Hinge Saddle Condyloid How do the bones of the skeletal system work?

  4. Skeletal System Articulation (joint): • A point of contact between two bones, between bone and cartilage, and between bone and teeth. • Joints are classified structurally based on their anatomical characteristics and their function. How do the bones of the skeletal system work?

  5. Skeletal System Joint Classifications: • Fibrous joints– made of tough collagen fibers and are immovable joints How do the bones of the skeletal system work?

  6. Skeletal System Joint Classifications: • Cartilaginous joints– made of cartilage - binds bone together and are slightly moveable

  7. Skeletal System Joint Classifications: • Synovial joints – have a fluid-filled space (synovial cavity) and are freely moveable joints

  8. Skeletal System Quick Check for Learning: Think/pair/share: What are the three classifications of joints and how do they differ from one another?

  9. Skeletal System Types of Synovial Joints: • Pivot Joint • Ball and Socket Joint • Hinge Joint • Saddle Joint • Condyloid Joint • Planar Joint How do the bones of the skeletal system work?

  10. Skeletal System Pivot Joint: The round surface of one bone articulates with a ring formed partly by another bone or partly by a ligament. Examples: atlas & axis of the vertebrae elbow joint at the head of the radius How do the bones of the skeletal system work?

  11. Skeletal System Ball-and-Socket Joint: The ball-like surface of one bone fits into the cuplike depression of another bone. Examples: Shoulder joint Hip joint How do the bones of the skeletal system work?

  12. Skeletal System Hinge Joint: The convex surface of one bone fits into the concave surface of another bone. Examples: elbow joint knee joint How do the bones of the skeletal system work?

  13. Skeletal System Quick Check for Learning: Give One / Get One Type of Synovial Joint and provide an example in the body How do the bones of the skeletal system work?

  14. Skeletal System Saddle Joint: The surface of one bone is saddle-shaped, and the surface of the other bone fits into the “saddle” as a sitting rider would sit. Example • Wrist and metacarpal of thumb How do the bones of the skeletal system work?

  15. Skeletal System Condyloid Joint: The convex oval-shaped projection of one bone fits into the oval-shaped depression of another bone. Example: Wrist Ankle How do the bones of the skeletal system work?

  16. Skeletal System Planar Joints: (Gliding joints): The opposed surfaces of the bones are flat or almost flat. These joints allow only gliding or sliding movements. Examples: carpals and tarsals How do the bones of the skeletal system work?

  17. Skeletal System Quick Check for Learning: Give One / Get One Type of Synovial Joint and provide an example in the body How do the bones of the skeletal system work?

  18. Skeletal System Types of Synovial Joints How do the bones of the skeletal system work?

  19. Skeletal System The Connectors: join bone to muscles and other bones. • Tendons – connects muscle to bone Example: achilles tendon isthe largest tendon in the body. How do the bones of the skeletal system work?

  20. Skeletal System The Connectors: join bone to muscles and other bones. • Ligaments– connect bones to other bones to form a joint. • Examples: ACL, MCL, • LCL. How do the bones of the skeletal system work?

  21. Skeletal System The Connectors: join bone to muscles and other bones. 3. Cartilage - covers the ends of all long bones How do the bones of the skeletal system work?

  22. Skeletal System Ticket Out the Door: • Using information and key vocabulary words presented in the last two lessons, write 5 lines (paragraph) to explain why different bone types, joints, and connectors are necessary for our body to function/move properly. How do the bones of the skeletal system work?
