Question

use the image. identify the bony landmark marked by the arrow.
a greater tubercle
b lesser tubercle
c medial epicondyle
d lateral epicodtyle

Explanation:

The image shows a humerus bone. The greater tubercle is a prominent bony landmark on the proximal humerus, typically more lateral and larger than the lesser tubercle. The arrow - marked structure (assuming typical humerus anatomy) corresponds to the greater tubercle. The lesser tubercle is more medial, and epicondyles are on the distal humerus, so options B, C, D are incorrect.

Answer:

A. greater tubercle
