tuberosity
large rounded projection; may be roughened
projections that are sites of muscle and ligament attachment
crest
narrow ridge of bone; usually prominent
projections that are sites of muscle and ligament attachment
trochantar
very large, blunt, irregularly shaped process (the only examples are on the femur)
- (projections that are sites of muscle and ligament attachment)
line
narrow ridge of bone; less prominent than a crest
projections that are sites of muscle and ligament attachment
tubercle
small rounded projection or process
projections that are sites of muscle and ligament attachment
epicondyle
raised area on or above a condyle
projections that are sites of muscle and ligament attachment
spine
sharp, slender, often pointed projection
process
any bony prominence
head

fossa
shallow basinlike depression in. abonel often serving as an articular surface

hyoid
looks like a mini mandible
- located immediately inferior to the mandible
- only bone in the skeleton tht does not articulate directly with another bone
