The supraoptic nucleus (SON) is a nucleus of magnocellular neurosecretory cells in the hypothalamus of the mammalian brain. The nucleus is situated at the base of the brain, adjacent to the optic chiasm. In humans, the SON contains about 3,000 neurons.
Jul 24, 2023 · The supraoptic nucleus is a collection of magnocellular neurosecretory cells (MNCs) located within the anterior hypothalamus that participate in the HPA axis. The primary function of these cells is to produce and secrete the peptide hormone vasopressin, also known as antidiuretic hormone (ADH) and oxytocin.

The supra-optic nuclei (SON) are on the border between the pre-optic area and the hypothalamus and sit bilaterally on the dorsal and lateral area of the optic chiasm. They secrete vasopressin in the face of increased osmolality and dehydration.
Jul 5, 2022 · The supraoptic nucleus (SON) contains neurosecretory cells that produce the hormone vasopressin/antidiuretic hormone (ADH). Gross anatomy. The supraoptic nucleus is found in the medial area of the anterior hypothalamus, sitting superior to the optic tract 1.
The supraoptic nucleus (SON) is a nucleus of magnocellular neurosecretory cells in the hypothalamus of the mammalian brain. The nucleus is situated at the base of the brain, adjacent to the optic chiasm. In humans, the SON contains about 3,000 neurons.
The supraoptic (SON) and paraventricular (PVN) nuclei of the hypothalamus undergo structural and functional changes over the course of healthy aging. These nuclei and their connections are also heterogeneously affected by several different neurodegenerative diseases.
