BONE MARKINGS Every bump, groove, and hole has a name on your bones p.137 Table 7.2
BONE MARKINGS • PROJECTIONS: • Processes that protrude out of bone • DEPRESSIONS • Cavities that indent into bone
PROCESS • PROCESS:A relatively large projection or prominent bump
Joint Projections • Condyle: Rounded articular projection Condyle A few slides ahead not the EPICONDYLE… Which would be found above a condyle
Joint Projections • Head: bony expansion on a narrow neck • Facet: smooth, nearly flat articular surface
Joint Projections • Ramus: Armlike bar of bone
Ligament/Tendon Projections Crest: Narrow ridge of bone (Line: smaller than a crest) Epicondyle: Raised area on or above a condyle ULNA
Tubercle: Small rounded projection Tuberosity: large rounded or roughened projection Trochanter: very large, blunt projection (only on femur) Proximal Tibia
PROJECTIONS Spine: Sharp, pointed projection Thoracic Vertebrae
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
DEPRESSIONS • Allow blood vessels or nerves to pass through. Meatus: (me - A- tus) Canal or tube
Depressions Fossa: shallow basin Fissure: narrow, slit-like opening
Depressions Sinus: Cavity within a bone; filled with air and lined with mucous membranes Foramen: Round or oval opening Foramen Magnum
DEPRESSIONS • FOVEA: a small pit or depression
Depressions Sulcus, Groove or Furrow: a shallow depression
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
