Potential space

Potential Space

Potential space (pronunciation: /pəˈten(t)SHəl/ /spās/) is a term used in anatomy to describe areas in the body where normally no space exists, but can be created when two adjacent structures separate.

Etymology

The term "potential space" is derived from the Latin word "potentia" meaning "power" and the Old French "espace" meaning "room, area, distance". It is used to describe the potential for a space to exist, rather than an actual existing space.
