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.

Jul 5, 2022 · The supraoptic nucleus (SON) contains neurosecretory cells that produce the hormone vasopressin/antidiuretic hormone (ADH). The supraoptic nucleus is found in the medial area of the anterior hypothalamus, sitting superior to the optic tract 1.

The supraoptic nucleus is a part of the hypothalamus that plays a regulatory role in maintaining fluid balance and controlling blood pressure. It is closely connected to the paraventricular area and contains vasopressin neurons.

The supraoptic nucleus (SON) in the human hypothalamus is an elongated, densely packed collection of large neurosecretory cells. ... total cell number and the mean diameter of the cell nuclei. No sexual differences were observed in any of these parameters with the exception that males have a more elongated SON than females. In contrast to ...

The primary function of these cells is to produce and secrete the peptide hormone vasopressin, also known as antidiuretic hormone (ADH) and oxytocin.

The supraoptic nucleus is a specialized cluster of magnocellular neurosecretory cells located within the hypothalamus, at the base of the brain near the optic chiasm. This nucleus plays a critical role in regulating renal water excretion, a process …

The supraoptic and paraventricular hypothalamic nuclei are the principal sources of the neurohypophysial hormones, oxytocin and vasopressin. In both nuclei, these hormones are synthesized in large (magnocellular) neurons that are critical for cardiovascular and body fluid homeostasis (vasopressin), parturition (oxytocin), and lactation (oxytocin).

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.

Jan 1, 2024 · The supraoptic nuclei (SON) are located bilaterally on the optic chiasm’s dorsal and lateral areas and between the preoptic area and the hypothalamus. The supraoptic nucleus further divides into the pars principalis, the pars intraoptica, and the pars tuberalis.
