In the limbs, which term describes a structure farther from the point of attachment?

Explanation:
In limbs, distance from where the limb attaches to the body defines the term distal. The trunk is the attachment point, so structures closer to the trunk are proximal, while those farther away along the limb are distal. Anterior and posterior describe front and back surfaces, not distance, so they don’t describe how far something is from the attachment. For example, the shoulder is proximal to the elbow, the elbow is proximal to the wrist, and the wrist is distal to the elbow, with the fingers distal to the wrist. Therefore, the structure farther from the attachment is distal.
