Anatomia

Sectione sagittali cerebri situs nuclei ventromedialis (VMN) immediate post nucleum supraopticum (SO) et ante nucleum posteriorem (PN) est.

Nucleus ventromedialis hypothalami (NVM) sive hypothalamus ventromedialis (HVM) est nucleus hypothalamicus.

Munera eius sensum satietatum, ut famum, timoris , activitatis sexualis, gubernationis temperaturae corporis velut alia endocrinea.

Nucleus ventromedialis hypothalami dimorphismum sexualem ostendit.

Anatomia microscopica

Nucleo ventromediali partes quattuor sunt:

pars anterior
pars centralis
pars dorsomedialis
pars ventrolateralis

Physiologia

Munus nuclei principale ventromedialis est sensum satietatis instituendi. Putatur, ut numerus circadianus ope inditorum a nucleo suprachiasmatico missorum etiam in nucleo ventromediali momentum habeat^[1].

Fames et satietas

Functionem satietas imprimis ad famem spectare constat.

Sexualitas

Functiones nuclei ventrolateralis multipliciter ad motus sexuales humanos et animum adigit. Praeterea dimorphismus sexualis narratum est.

Dimorphismus sexualis

In rattis femininis, per exemplum, nucleus reflexum lordosis (dorsiflexionem rattorum femininorum oestro ineunte facilius facit^[2].

Rattis masculinis receptoria androgeni sunt^[3].
