Inferior olivary nucleus
A large convoluted mass of gray matter lying in the ventral part of the medulla oblongata and forming part of the reticular system. It gives rise to fibers of the olivocerebellar tract.
-
Hypothalamic nucleus
One of the nuclei occurring in four groups found in the hypothalamus. Hypothalamic nuclei include the dorsomedial, intercalatus, lateral, mamillary (lateral and medial), paraventricular, posterior, supraoptic, tuberal, and ventromedial. The cells of these nuclei secrete oxytocin and antidiuretic hormone. These hormones pass through the efferent fibers of the infundibular stalk to the posterior lobe of…

Hypoglossal nucleus
An elongated mass of gray matter in the medulla oblongata in the floor of the fourth ventricle, giving rise to the motor fibers of the hypoglossal nerve.
-
Haploid nucleus
A cell nucleus with half the normal number of chromosomes, as in germ cells (ova and sperm) following the normal reduction divisions in gametogenesis.
-
Habenular nucleus
A nucleus of the diencephalon located in the habenular trigone. It is an olfactory correlation center.
-
Globose nucleus
A nucleus of the cerebellum located medial to the emboliform nucleus.
-
Germinal nucleus
A nucleus resulting from the union of male and female pronuclei.
-
Free nucleus
A nucleus that is no longer surrounded by the other cellular components.
-
Fertilization nucleus
A nucleus produced by the joining of the male and female nuclei in the fertilization of the ovum.
-
Fastigial nucleus
A nucleus in the medullary portion of the cerebellum that receives afferent fibers from the vestibular nerve and superior vestibular nucleus. The afferent fibers form the fasciculus uncinatus and the fastigiobulbar tract.
