Uberon definition : A specialized brain region of the ventral diencephalon arising near the end of the
segmentation period; the embryonic hypothalamic region will give rise to the posterior
pituitary gland as well as a number of brain nuclei. [ZFA]. One of the most important
functions of the hypothalamus is to link the nervous system to the endocrine system
via the pituitary gland (hypophysis).[Wikipedia].;
Uberon Homology note : For instance, the vertebrate ventral diencephalon generates the hypothalamus which
functions as a major endocrine center in cooperation with the hypophysis, the anterior
part of the pituitary gland, located just ventral to the hypothalamus. In the amphioxus
brain, the presence of a hypothalamus-like structure has been reported associated
with the ventrally located Hatschek's pit, the hypothetical hypophysial homologue.
It is thus conceivable that a hypothalamus-like structure originally involved in endocrine
functions may have already been present before the establishment of vertebrates.[well
established][VHOG];
Uberon Taxon note : all vertebrates contain a hypothalamus;
