Abstract:
The meaning and usefulness of the phrase "an anatomical space" are questioned. The concept of anatomical space is examined from historical, developmental, and topographical viewpoints. The validity of the idea and usage of the term "potential space" is discussed. The criterion of Haines (1991) is adopted, 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 anatomical "spaces" be designated "compartments."

Body Planes
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
Anatomy of the Brain: Major Regions
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect various areas...
