What does the term proximal signify when referring to anatomical structure?

The term proximal is used in anatomy to describe a position that is nearer to the trunk of the body or the point of origin of a structure. In the context of limbs, for example, the shoulder is proximal to the elbow because it is closer to the center of the body. This term helps to establish a clear understanding of the relative locations of various body parts. Proximal is often contrasted with distal, which refers to structures that are further away from the trunk or point of origin. Understanding this terminology is essential for effectively communicating about human anatomy and the relationships between different body parts.
