[TA]
the portion of the hypothalamus located generally internal to the region of the mammillary bodies; contains the following nuclei: dorsal premammillary nucleus [TA] (nucleus premammillaris dorsalis [TA]), lateral nucleus of mammillary body [TA] (nucleus mammillaris medialis [TA]), supramammillary nucleus [TA] (nucleus supramammillaris [TA]_, and the ventral premammillary nucleus [TA] (nucleus premammillaris ventralis [TA]). The posterior nucleus of hypothalamus [TA] is located at the interface of intermediate and posterior hypothalamic areas and is sometimes considered a part of the latter.
