The supraoptic nucleus is an important "model system" in neuroscience. There are many reasons for this: Some technical advantages of working on the supraoptic nucleus are that the cell bodies are relatively large, the cells make exceptionally large amounts of their secretory products, and the nucleus is relatively homogeneous and easy to ...
Chief or pontine nucleus of the trigeminal nerve sensory nucleus (V) Motor nucleus for the trigeminal nerve (V) Abducens nucleus (VI) Facial nerve nucleus (VII) Vestibulocochlear nuclei (vestibular nuclei and cochlear nuclei) (VIII) Superior salivatory nucleus; Pontine tegmentum. Pontine micturition center (Barrington's nucleus) Locus coeruleus
The suprachiasmatic nucleus or nuclei (SCN) is a small region of the brain in the hypothalamus, situated directly above the optic chiasm. It is responsible for regulating sleep cycles in animals. [ 1 ] [ 2 ] Reception of light inputs from photosensitive retinal ganglion cells allow it to coordinate the subordinate cellular clocks of the body ...
Magnocellular neurosecretory cells are large neuroendocrine cells within the supraoptic nucleus and paraventricular nucleus of the hypothalamus.They are also found in smaller numbers in accessory cell groups between these two nuclei, the largest one being the circular nucleus. [1]
The paraventricular nucleus of hypothalamus (PVN, PVA, or PVH) is a nucleus in the hypothalamus, that lies next to the third ventricle. Many of its neurons project to the posterior pituitary where they secrete oxytocin , and a smaller amount of vasopressin .
Parvocellular neurosecretory cells are small neurons that produce hypothalamic releasing and inhibiting hormones. The cell bodies of these neurons are located in various nuclei of the hypothalamus or in closely related areas of the basal brain, mainly in the medial zone of the hypothalamus.
[2] [3] It overlies the paraventricular nucleus of hypothalamus, [4] and is involved in the secretion of vasopressin. [2] The VOLT monitors the presence of peptides and macromolecules in the bloodstream, and conveys the information to the hypothalamus. [3] It is one of the three sensory circumventricular organs of the brain. [5] The other four ...
The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: . paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus
