What is the definition of an osseous malleolus?
A hammerhead-like elevation on the surface of bone
What are the categories of sharp osseous elevations?
Spine and process
What is the definition of an osseous process?
A relatively sharp bony projection from the surface of bone with an increased length
What are the categories or osseous depressions?
Linear and rounded depressions
What is the definition of an osseous sulcus?
A wide groove of variable length and depth on the surface of bone
What are the categories of rounded osseous depressions?
The fovea and fossa
What is the definition of an osseous fovea?
A shallow depression of variable circumference on the surface of bone
What is the definition of an osseous fossa?
A deep depression of variable circumference on the surface of bone
What are the names given to openings on the surface of bone?
Ostium or orifice and hiatus
What is the definition of an osseous hiatus?
An irregular opening on the surface of bone.
What are the names given to osseous ostia which completely penetrate the bone?
Foramen or canal
What is the definition of an osseous Foramen
An ostium passing completely through a thin region of bone
What is the definition of an osseous canal?
An ostium passing completely through a thick region of bone
What is the name given to an ostium which does not completely penetrate through a region of bone but appears as a blind-ended passageway?
Meatus
What is the definition of an osseous fissure?
An irregular slit-like or crack-like appearance between the surface of adjacent bones
What are the categories of osseous facets?
Flat and rounded
What are the categories of rounded osseous facets?
Articular heads and articular condyles
What is the definition of an osseous condyle?
A knuckle-shaped surface on bone for osseous articulation
What are the categories of osseous linear depressions?
Notch or incisive, groove, and sulcus
When do surface features of bone become prominent?
During and after puberty
What is the definition of an osseous tubercle?
A small raised elevation from the surface of bone, usually associated with the attachment of a ligament or tendon
What is the definition of an osseous protuberance?
Rounded elevation from the surface of bone with a larger base that appears as a swelling or knob
