  1. SKELETAL SYSTEM

  2. Cool x-rays

  3. Function • Provides frame and support for all systems and organs. Skeletal System

  4. Ligaments • Connect bones together; tough tissue • Tendons • Connects bones to muscles Skeletal System

  5. Bone • Attach muscles • Means of movement • Protect internal organs • Storage of minerals • Cartilage • Firm, flexible tissues that is not as hard as bone Skeletal System

  6. Skeletal System • Layers of Bone • Periosteum • Outer layer • Cushions the hard portion of the bone • Repair of broken bones

  7. Skeletal System • Layers of Bone • Compact Bone • beneath periosteum • layer of hard mineral matter • Calcium • gives bones strength

  8. Skeletal System • Layers of Bone • Spongy Bone • Inside hard outer layer • fills ends of bones • lines hollow portions

  9. Skeletal System • Layers of Bone • Red marrow • inside cavities of spongy bone • formation of red blood cells

  10. Skeletal System • Layers of Bone • Yellow marrow • Located inside hollow portion • Fat storage cells • Energy storage

  12. SKELETAL SYSTEM

  13. Skeletal System • Types of Bone • Long Bones • Longest • Provide support and movement • Levers • Example -- legs, ribs, pelvic bones

  14. Skeletal System • Types of Bone • Short Bones • Smaller than long bones • Joints • Comfort and mobility • Example -- feet and hands

  15. Skeletal System • Types of Bone • Irregular Bones • Have an irregular shape • Support and protect • Example -- vertebrae

  16. Skeletal System • Types of Bone • Flat Bones • Thin and flat • Protect organs • Example -- skull

  17. Joints • Where different bones meet • Classified by the way they move. Skeletal System

  18. Hinge Joint

  19. Ball and Socket

  20. Gliding

  21. The skeleton is divided into two parts: • The axial skeleton protects the major organs of the nervous, respiratory, and circulatory systems • The axial skeleton consists of the skull, hyoid bones, vertebral column, ribs, and sternum • The appendicular skeleton is the framework that consists of the extremities, shoulder, and pelvic girdle • Appen means to add or hang • The appendicular skeleton includes the bones of the front and hind limbs The Skeleton

  22. The Axial Skeleton • The cranium is the portion of the skull that encloses the brain

  23. The Axial Skeleton • The vertebral column supports the head and body and provides protection for the spinal cord • The vertebral column is comprised of individual bones called vertebra

  24. The Appendicular Skeleton • Front limb • scapula • clavicle • humerus • radius • ulna • carpal bones • metacarpal bones • cannon bone in livestock • phalanges

  25. The Appendicular Skeleton • Hind limb • pelvis • femur • patella • tibia • fibula • tarsal bones • metatarsal bones • cannon bone in livestock • phalanges
