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
