Presentation Transcript

  1. Bone Markings • Surface features of bones • Sites of attachments for muscles, tendons, and ligaments • Passages for nerves and blood vessels • Categories of bone markings • Projections or processes — grow out from the bone surface • Depressions or cavities — indentations

  2. Bone Surface Markings • projections where muscles, tendons, ligaments attach • tuberosity – large rounded projection • spinous process (or spine) – sharp, slender, pointed projection • trochanter – very large, blunt irregular shaped projection • crest – narrow ridge of bone

  3. Bone Surface Markings • Projections that help to form joints • Head – bony expansion at the end of a long neck • Facet – smooth, almost flat surface • Condyle – rounded projection • Ramus – armlike arm of bone

  4. Bone Surface Markings • Depressions and openings fro blood vessels and nerves to pass through • Foramen – round or oval opening in a bone • Meatus – canal-like • Fossa – shallow depression mostly to form a joint
