Verified step by step guidance
1
Understand the anatomy of the humerus: The humerus is the long bone in the upper arm, connecting the shoulder to the elbow. It has proximal and distal ends, with distinct features at each end.
Define the proximal end of the humerus: The proximal end is the part of the humerus closest to the shoulder joint. It includes structures such as the head of the humerus, the anatomical neck, and various tubercles.
Identify the greater tubercle: The greater tubercle is a prominent projection located on the lateral side of the proximal end of the humerus. It serves as an attachment site for muscles like the supraspinatus, infraspinatus, and teres minor.
Compare the other options: The medial epicondyle is located at the distal end of the humerus near the elbow. The olecranon fossa is also at the distal end, serving as a depression for the olecranon process of the ulna. The capitulum is a rounded structure at the distal end that articulates with the radius.
Conclude that the greater tubercle is the correct answer: Since the greater tubercle is located at the proximal end of the humerus, it is the correct feature based on the question.
