Definitions specific to this category can be found in Definitions/Laminae.

A lamina is an ideal of a (rigid) body embedded in ordinary space such that one of its dimensions is infinitesimal.

That is, its thickness can be considered to be uniform and positive, but small enough to be ignored.

Such a lamina can be interpreted as a body which is all surface.

Thus it has area and (area mass) density but zero thickness.
