Anatomical spaces: A review

The meaning and usefulness of the phrase "an anatomical space" are question ed. The concept of anatomical space is examined from historical, developmen tal, and topographical viewpoints. The validity of the idea and usage of th e term "potential space" is discussed. The criterion of Haines (1991) is ad opted, that only "spaces" or "cavities" that are lined with a "mesothelial" layer and that can repeatedly be opened up without tissue damage should be considered "true potential spaces." A plea is made that all other anatomic al "spaces" be designated "compartments." Clin. Anat. 12:66-69, 1999. (C) 1 999 Wiley-Liss, Inc.
