  1. BONE MARKINGS Every bump, groove, and hole has a name on your bones p.137 Table 7.2

  2. BONE MARKINGS • PROJECTIONS: • Processes that protrude out of bone • DEPRESSIONS • Cavities that indent into bone

  3. PROCESS • PROCESS:A relatively large projection or prominent bump

  4. Joint Projections • Condyle: Rounded articular projection Condyle A few slides ahead not the EPICONDYLE… Which would be found above a condyle

  5. Joint Projections • Head: bony expansion on a narrow neck • Facet: smooth, nearly flat articular surface

  6. Joint Projections • Ramus: Armlike bar of bone

  7. Ligament/Tendon Projections Crest: Narrow ridge of bone (Line: smaller than a crest) Epicondyle: Raised area on or above a condyle ULNA

  8. Tubercle: Small rounded projection Tuberosity: large rounded or roughened projection Trochanter: very large, blunt projection (only on femur) Proximal Tibia

  9. PROJECTIONS Spine: Sharp, pointed projection Thoracic Vertebrae

  10. MARKINGS ON THE CRANIUM Fontanel :soft spot in the skull (infant skull)…cranial bones have not yet fused • Suture: interlocking line at the union of 2 bones; fibrous joint in the skull

  11. DEPRESSIONS • Allow blood vessels or nerves to pass through. Meatus: (me - A- tus) Canal or tube

  12. Depressions Fossa: shallow basin Fissure: narrow, slit-like opening

  13. Depressions Sinus: Cavity within a bone; filled with air and lined with mucous membranes Foramen: Round or oval opening Foramen Magnum

  14. DEPRESSIONS • FOVEA: a small pit or depression

  15. Depressions Sulcus, Groove or Furrow: a shallow depression

  16. Review: (note on your index cards which markings are projections & which are depressions) Projections • Process • Condyle • Head • Facet • Ramus • Crest • Epicondyle • Tubercle • Tuberosity • Trochanter • Spine Depressions • Meatus • Fossa • Fovea • Fissure • Foramen • Sinus • Fontanel • Suture • Sulcus or Groove or Furrow
