Verified step by step guidance

Begin by identifying the anatomical location of the humerus and ulna in the human body. The humerus is the upper arm bone, while the ulna is one of the two bones in the forearm.

Understand the concept of articulation in anatomy, which refers to the connection between bones at a joint. The humerus and ulna articulate at the elbow joint.

Examine the distal end of the humerus, which is the part that connects with the forearm bones. This end has several structures that facilitate articulation.

Identify the trochlea on the distal end of the humerus. The trochlea is a spool-shaped structure that specifically articulates with the ulna, allowing for hinge-like movement at the elbow joint.

Differentiate the trochlea from other structures such as the capitulum, which articulates with the radius, and fossae like the coronoid and olecranon, which accommodate projections of the ulna during movement.
