I'd say "medical knowledge" is too broad of a term to define a finite full spectrum in reasonable terms, as it effectively includes every possible interaction of each part of the human body with every type of physical or chemical condition. More reasonable would be to talk about "anatomical knowledge", which is finitely bound to understanding the expected structure/distribution, function of and communication between each part of the human body to a sub-cell level. We're most of the way there on the first facet, but our models of the latter two are still hilariously incomplete at this point.
