elevations, depressions, tunnels or passageways and facets
When do the surface features of bone become prominent?
during and after puberty
What are the types of osseous elevations?
linear, rounded, and sharp
What are the types of osseous linear elevations?
line, ridge, and crest
What are the types of rounded osseous elevations?
tubercle, protuberance, trochanter, tuber or tuberosity and malleolus
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
What is the definition of an osseous malleolus?
hammer-head 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 trochanter?
large, blunt projection from the surface of bone with a significant base and height
What is the definition of an osseous tuber or tuberosity?
large projection with a significant base and variable height on the surface of bone
What is the definition of an osseous malleolus?
hammer-head like elevation on the surface of bone
What is the definition of the osseous elevation called spine?
thorn like elevation from the surface of bone
What is the definition of an osseous process?
relatively sharp bony projection from the surface of bone with an increased length.
what are the categories of osseous depressions?
linear and rounded depressions
What are the categories of osseous linear depressions?
notch or incisor, groove, and sulcus
What is the definition of an osseous surface notch or incisor?
a short indentation of variable depth on the surface of bone
What is the definition of an osseous groove?
a long furrow of variable depth on the surface of a bone
What is the categories of rounded osseous depressions?
fovea and fossa
Definition of osseous fovea?
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?
osmium or orifice and hiatus
What is the definition of and osseous ostium?
a round or oval opening on the surface of bone
what is the definition of an osseous hiatus?
irregular opening on the surface of bone
What are the names given to osseous ostia which completely penetrate bone?
foramen or canal
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 a osseous meatus?
blind ended passageway that does not completely penetrate through a bone
What is the definition of an osseous fissure?
irregular slit-like or crack-like appearance between the surfaces of adjacent bones
What are the categories of rounded osseous facets?
