Verified step by step guidance

Understand the anatomical terminology: 'distal' refers to a position farther from the trunk of the body or the point of attachment.
Identify the features of the humerus listed in the options: Greater tubercle, Deltoid tuberosity, Head of the humerus, and Lateral epicondyle.
Locate each feature on the humerus: The head of the humerus is proximal, articulating with the scapula. The greater tubercle is near the head, also proximal. The deltoid tuberosity is located along the shaft of the humerus, more distal than the head and tubercle.
Recognize that the lateral epicondyle is located at the distal end of the humerus, near the elbow joint.
Conclude that the lateral epicondyle is the most distal feature among the options provided, as it is located farthest from the trunk of the body.
