In anatomical terms, what does "proximal" refer to?

The term "proximal" refers to the positioning of a structure in relation to its point of attachment or origin. In anatomical terminology, when something is described as proximal, it means that it is situated nearest to where it connects to the trunk of the body or the point of origin within that system. For instance, in the context of the limbs, the shoulder is proximal to the elbow because it is closer to the body's core. This term is essential for accurately describing locations and movements within the body, especially in fields like anatomy, physical therapy, and medicine. Understanding the concept of proximity is critical for professionals when communicating about the body’s structure and function.
