[2] Anencephaly is classically subdivided into two forms: holo-anencephaly (complete absence of forebrain and cranium) and mero-anencephaly, in which "the cranium and the brain are present in rudimentary form." [3] Others employ the related terms "holoacrania" and "meroacrania," referring to the degree of bone absence.
In particular, mero-anencephaly (meroacrania), which involves only a partial absence of brain and calvarium, by definition admits of degrees to which both these structures may be present.
