Click on any nucleus to see its location

• Preoptic nucleus
• Suprachiasmatic nucleus
• Paraventricular nucleus
• Anterior nucleus
• Supraoptic nucleus

• Dorsomedial nucleus
• Ventromedial nucleus
• Arcuate nucleus
• Posterior nucleus
• Mammillary nucleus
• All nuclei

For each nucleus, two diagrams are given from two
different sources. The gross location of nuclei
and their relationships are same in both
diagrams there are minor variations in shape of
some nuclei. Lateral nucleus is shown in only one
diagram.
