1 Ventromedial hypothalamic nucleus. Nucleus hypothalamicus ventromedialis. Lies in and above the entrance into the infundibulum. This nucleus belongs to the group of tuberal nuclei and, like them,controls the release ofregulating hormones for the anterior lobe via the hypophy-sial stalk. A
2 Dorsomedial hypothalamic nucleus. Nucleus hypothalamicus dorsomedialis. It lies near the apex ofthe ventromedial hypothalamic nucleus and has similar functions. A
3 Dorsal hypothalamic nucleus. Nucleus hy-pothalamicus dorsalis. Group of cells located below the dorsal hypothalamic area (see p. 302.14). A
4 Posterior periventricular nucleus. Nucleus periventricularis posterior. Cell group located below the ependyma in the posterior segment of the 3rd ventricle. A
5 Infundibular (arcuate) nucleus. Nucleus infun-dibularis (arcuatus). It lies near the apex of the funnel of the infundibulum and has functions similar to those of the tuberal nuclei. A
6 Posterior hypothalamic area. Regio hy-pothalamica posterior. It contains the lateral and medial nuclei of the mamillary body and other structures.
7 Medial and lateral nuclei of mamillary body. Nuclei corporis mamillaris mediales/laterales. The medial nucleus forms the mamillary body and is the origin of the mamillothalamic fasciculus. The lateral nucleus lies ventrolateral and receives the fornix. AB
8 Posterior hypothalamic nucleus. Nucleus hy-pothalamicus posterior. It lies occipital to the dorsomedial and ventromedial nuclei and above the mamillary body up to the hy-pothalamic sulcus and influences circulation, peristalsis and the blood sugar level. A B
9 Neurohypophysis. In contrast to the two other posterior lobes of the hypophysis, it is of neurogenic origin; so is the continuation of the infun-dibulum. B
10 Hypothalamic tract and fasciculi. Tractus et fasciculi hypothalamici. Tracts and fiber bundles of the hypothalamus.
11 Periventricular fibers. Fibrae periventriculares. Fiber tract directly under the ependyma of the 3rd ventricle. It is permeated by cells, connects the thalamus with the hypothalamus and continues posteriorly into the posterior longitudinal fasciculus. B
12 Dorsal supraoptic commissure. Commissura supraoptica dorsalis [[Meynert]]. Decussation lying directly above the chiasm. Passes to the other side and may connect the subthalamic nucleus with the contralateral globus pallidus.
13 Ventral supraoptic commissure. Commissura supraoptica ventralis [[ Gudden]]. Crossing fibers lying partially in the chiasm. Among other things, it may connect the medial geniculate bodies with one another.
