1. Bone Surface Features Flashcards
What are the four basic surface feature categories?
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 elevation?
the 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 tubercle?
a small raises elevation from the surface of a 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
What is the definition of an osseous trochanter?
a large, blunt projection from the surface of bone with a significant base and height
What is the definition of an osseous tuber or tuberosity?
a large projection with a significant base and a variable height on the surface of bone
What are examples of osseous tubers or tuberosities?
the frontal tuber of the frontal bone, tuberosity for the serratus anterior muscle on rib 2, the sacral tuberosity of S2, and the ischial tuberosity of the innominate bones
What is the definition of an osseous malleolus?
a hammerhead-like elevation on the surface of the bone
What are examples of an osseous malleolus?
the medial malleolus of the tibia and lateral malleolus of the fibula
What are the categories of sharp osseous elevations?
spine and process
What is the definition of the osseous elevation called “spine”?
a thorn-like elevation from the surface of the bone
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 of osseous depressions?
linear and rounded depressions
What are the categories of osseous linear depressions?
notch or incisure, groove, and sulcus
What are the categories of rounded osseous depressions?
the fovea and the fossa
What is the definition of an osseous fovea?
a shallow depression of variable circumference on the surface of bone
What are the names fiven to openings on the surface of bone?
ostium or orifice and hiatus
What is the defintion of an osseous hiatus?
an irregular opening on the surface of bone
What are the names given to oseeous ostia which completely penetrate bone?
foramen or canal
What is the defintion 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 surfaces of adjacent bones
What are the categories of osseous facets?
flat facets and rounded facets
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
