Presentation Transcript

  1. Bone and Muscle Features

  2. Some Surface Features of Bones • Processes • Lines • Foramina • Sinuses • Fossa • Sutures

  3. Bone Process • Area where the bone has extra tissue • Projections • Can help form joints • Can provide attachment sites for muscles and ligaments

  4. Bone line • Groove in the bone from other developmental processes • A narrow, low ridge

  5. Bone Foramina • Holes in the bones through which nerves and blood vessels pass • Ligaments may also pass through

  6. Bone sinuses • Empty spaces in the bones that make the skull lighter • Cavity within a bone

  7. Bone fossa • A relatively deep pit or depression

  8. Bone sutures • An interlocking line of union between bones

  9. Muscle features (skeletal) • Striations • Tendons • Origin • Insertion

  10. Muscle striations • Skeletal & cardiac muscle only • The striations seen in skeletal muscle fibers are the result of the alignment of hundreds of myofibrils (long protein strands) within each muscle fiber.

  11. Tendons • A tough band of fibrous connective tissue that usually connects muscle to bone.

  12. Origin • Where the muscle attaches to the bone

  13. Insertion • Where the muscle meets a tendon
