Question

select the correct answer.
in this diagram of a long bone, which type of bone marking is circled?
bone marking
a. foramen
b. fossa
c. osteon
d. tubercle

Explanation:

A foramen is an opening (hole) in a bone that allows nerves and blood vessels to pass through. In the diagram of the long bone, the circled marking is a foramen as it represents such an opening. A fossa is a depression, an osteon is a structural unit of compact bone (not a bone marking in the context of openings/depressions/projections here), and a tubercle is a small rounded projection. So the correct answer is A.

Answer:

A. foramen
