What does 'proximal' indicate in medical terminology?

In medical terminology, the term 'proximal' is used to describe a location that is closer to the center of the body or to a specific point of reference, such as a joint or the trunk. This positioning is crucial for understanding anatomy, especially when discussing the relative locations of different structures in the body.

For example, when talking about the arm, the elbow is considered proximal to the wrist because it is closer to the center of the body. This understanding helps healthcare professionals accurately describe the locations of injuries, diseases, or other conditions relative to the body’s core structures.

The other options describe positions that are either further from the center or refer to different anatomical planes, which do not align with the anatomical definition of 'proximal.'
