crest of bone
prominent ridge or elongated projection
Trochanter
Very large, blunt, irregularly shaped process
epicondyle
Raised area on or above a condyle
Lateral epicondylitis
-tennis elbow
-inflammation of the common extensors with origin at the lateral epicondyle
-frequent resistive extension motion or repetitive activities not trained
Joint Projections
-head
-facet
-condyle
-ramus
Head (bone marking)
prominent, rounded, articulating end of a bone
facet bone marking
smooth, nearly flat articular surface
condyle

-fovea
groove
shallow linear channel
fissure
Narrow, slitlike opening
foramen
Round or oval opening through a bone
notch
indentation at the edge of a bone
