Mar 20, 2021 · The terms proximal and distal are used in structures that are considered to have a beginning and an end (such as the upper limb, lower limb and blood vessels). They describe the position of a structure with reference to its origin – proximal means closer to its origin, distal means further away.
In simple terms, proximal means that one thing is closer to the center than another, and distal implies that one thing is further away from the center. Proximal = nearest to, closest to, or in proximity to (closest to the center of the body or torso)
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. Thus the upper arm in humans is proximal and the hand is distal.
If you’re at a clinical experience or even working a nursing shift, you need to understand the key differences between the terms proximal and distal to provide life-saving care in certain circumstances. Here are two examples to help you better understand how to use these terms.
Proximal describes a position in a limb that is nearer to the point of attachment or the trunk of the body. The brachium is proximal to the antebrachium. Distal describes a position in a limb that is farther from the point of attachment or the trunk of the body. The crus is distal to the femur.

Jan 17, 2023 · Proximal refers to a feature that is closer to the torso, while distal refers to a feature that is closer to the fingers/toes. Medial and lateral refer to position relative to the midline, which is a vertical line drawn through the center of the forehead, down through the belly button to the floor.
Nov 23, 2022 · Directional terms refer to the relative locations of different body structures. 2 Essentially, they explain how close or far away different structures are from one another. Anterior and posterior are terms used to describe whether a structure is in front of or behind another.
Nov 22, 2022 · Such terms include posterior or dorsal, which means towards the back of the body, or proximal and distal, which describe how close or far away something is, respectively. The standard anatomical position creates clear points of reference which help to avoid confusion when using anatomical terms.
Dec 5, 2022 · For example, the knee is proximal to the ankle, and the proximal aspect of a nerve is its origin. The opposite term of proximal is distal. This term describes the position of the structure that is further away from the trunk or the point of origin.
