Notes:

Here is how they are in the Metathesaurus. The Read vocabulary (clinical vocabulary from Britain) has additional terms with identical meaning to the concepts represented in the MeSH descriptor.

Note that we now have two concepts. The Unique Identifier (C number)

on them is a permanent assignment to this meaning. It is, “the name that never chanes.”
