  • Slide 2 - Things to Know: Oste “bone” Art “joint” -blast “germ” or embryonic -clast “broken” -cyte “cell” Peri- “around” Dia- “between or across” Epi- “upon” Hemat- “blood”
  • Slide 3 - The Skeletal System Parts of the skeletal system Bones (skeleton) Joints (flexibility) Cartilages (cushion) Ligaments (connect bone to bone)
  • Slide 4 - Functions of Bones Support the body (internal framework) Protect soft organs (vertebrae) L Allow movement due to attached skeletal muscles Store minerals and fats (fats, calcium, phosphorus) Hematopoiesis (Blood cell formation)
  • Slide 5 - The Skeletal System Two subdivisions of the skeleton 1. Axial skeleton (skull, ribs, spine) 2. Appendicular skeleton (pectoral girdle, pelvic girdle, bones of limbs)
  • Slide 6 - Figure 5.1a Shaft Head Head Long bones Have a shaft with heads at both ends Typically longer than they are wide Contain mostly compact bone Examples: Femur (longest bone in the body) Classification of Bones by Shape
  • Slide 7 - Anatomy of a Long Bone Diaphysis Compact bone Protected by periosteum (membrane) Epiphysis Ends of the bone Thin layer of compact bone But mainly spongy bone in the middle Protected by articular cartilage
  • Slide 8 - Anatomy of a Long Bone Medullary cavity Cavity inside of the diaphysis Contains yellow marrow (mostly adipose) in adults Contains red marrow (for blood cell formation) in infants
  • Slide 9 - Figure 5.1b 2. Short bones Generally cube-shape Contain mostly spongy bone Example: Carpals Tarsals Patella
  • Slide 10 - 3. Flat bones Thin, flattened, and usually curved Two thin layers of compact bone inside Layer of spongy bone inside Example: Skull Ribs Sternum
  • Slide 11 - 4. Irregular bones Irregular shape Do not fit into other bone classification categories Example: Vertebrae Hip bones
