Directional Terms Used in Anatomy:

Directional terms are terms used by anatomists to describe the position of one body part relative to another. Most directional terms are grouped into pairs and have opposite meanings. For example, superior means toward the upper part of the body, while inferior means toward the lower part of the body. Directional terms must be used to describe the position of one body part or structure relative to another. For example, "My knee is superior," makes no anatomical sense. The correct statement would be, "My knee is superior to my ankle."
