The term proximal is a directional term that is used to describe a position of a structure that is closer either to the center of the trunk of the body or to the point of origin. In addition, it can also describe a position that is closer to the central aspect of a linear structure.
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.
|Examples||Proximal phalanges, proximal part of prostatic urethra|
