Proximal vs. Distal Example #1 Using your arm as an example, we’ll compare the distance between your shoulder, elbow, wrist, and hand and determine whether or not one attachment is closer to the point of origin (torso) than another.
The terms proximal (from Latin proximus 'nearest') and distal (from Latin distare 'to stand away from') are used to describe parts of a feature that are close to or distant from the main mass of the body, respectively. [29] Thus the upper arm in humans is proximal and the hand is distal.

20 sie 2024 · Key Takeaways. Proximal and distal are terms used to describe the location of anatomical structures. The terms help provide clear communication, especially relevant in medical contexts. They are reflective of a structure’s position relative to the center of the body or another reference point.
Distal and proximal are terms used to describe the relative positions of two objects or points in space. Distal refers to a position that is farther away from a point of reference, while proximal refers to a position that is closer to a point of reference.
