Which of the following landmarks is found on the proximal end of the humerus?

• A. Radial tuberosity
• B. Olecranon
• C. Medial epicondyle
• D. Greater tubercle

Answer: (D)

Verified step by step guidance

1. Begin by identifying the anatomical location of the humerus. The humerus is the long bone in the upper arm, extending from the shoulder to the elbow.
2. Understand the terms 'proximal' and 'distal'. 'Proximal' refers to a position closer to the center of the body or point of attachment, while 'distal' refers to a position further away.
3. Examine the proximal end of the humerus, which is the end closer to the shoulder joint. This area includes several key landmarks.
4. Review the landmarks listed in the problem: Radial tuberosity, Olecranon, Medial epicondyle, and Greater tubercle. Note that the radial tuberosity is found on the radius, the olecranon is part of the ulna, and the medial epicondyle is located at the distal end of the humerus.
5. Identify the Greater tubercle as the correct landmark located on the proximal end of the humerus. It is a prominent area for muscle attachment near the shoulder joint.
