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
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
