Verified step by step guidance

Understand the anatomy of the humerus: The humerus is the long bone of the upper arm, and its distal end is involved in forming the elbow joint. Familiarize yourself with the key anatomical features located at the distal end of the humerus.

Identify the trochlea: The trochlea is a pulley-shaped structure located at the distal end of the humerus. It is specifically designed to articulate with the ulna, forming part of the hinge joint at the elbow.

Differentiate the trochlea from other features: The greater tubercle is located at the proximal end of the humerus and serves as an attachment site for muscles. The deltoid tuberosity is a roughened area on the shaft of the humerus where the deltoid muscle attaches. The capitulum is another structure at the distal end of the humerus, but it articulates with the radius, not the ulna.

Focus on the ulna articulation: Since the question asks for the feature that articulates with the ulna, the trochlea is the correct anatomical structure. The ulna fits into the trochlea to allow flexion and extension at the elbow joint.

Review the options provided: Based on the anatomical relationships, eliminate the incorrect options (greater tubercle, deltoid tuberosity, and capitulum) and confirm that the trochlea is the correct answer.
