Which anatomical term refers to a position nearer to the point where a limb attaches to the trunk?

A Distal

B Lateral

C Medial

D Proximal

Solution

Correct Answer: Option D

The correct answer is Proximal.

- In anatomical terminology, the term proximal refers to a position that is closer to the point where a limb attaches to the trunk of the body.
- This is important when describing locations along the limbs. For example, the elbow is proximal to the wrist because it is closer to the shoulder, which is the point of attachment of the arm to the trunk.

- In contrast, distal means farther away from the trunk or point of attachment.
- So the wrist is distal to the elbow. The terms medial and lateral refer to the position relative to the midline of the body — medial meaning closer to the midline and lateral meaning farther from the midline.

Understanding these terms is fundamental in anatomy for clearly describing the location and relation of structures.
