The arcuate nucleus is an aggregation of neurons in the mediobasal hypothalamus, adjacent to the third ventricle and the median eminence. The arcuate nucleus includes several important and diverse populations of neurons that help mediate different neuroendocrine and physiological functions, including neuroendocrine neurons, centrally projecting ...

The arcuate nucleus of hypothalamus (ARH) consists of neuroendocrine neurons and centrally-projecting neurons. The ARH is the center where the homeostasis of nutrition/metabolism and reproduction are maintained.

Green: arcuate nucleus (ARC), first-order center. Blue: lateral hypothalamus (LH) and dorsomedial nucleus (DMN), orexigenic or hunger centers.

The arcuate nucleus (ARC), located at the base of the hypothalamus on either side of the third cerebroventricle, is the most important site in the hypothalamic integration of energy balance.

Jan 15, 2022 · Schematic illustration of arcuate nucleus (ARC) POMC signalling for regulation of feeding activity via leptin and insulin action. Adipose-derived leptin binds to its specific receptor LepRb located near ARC membrane.

Immediately bordering the third ventricle, just inside of the ependymal cell lining, is a thin layer of cells that comprise the periventricular zone. This zone contains few distinct nuclei, but two that are very prominent are the arcuate nucleus and the paraventricular nucleus, which are involved in neuroendocrine and autonomic regulation.

The arcuate nucleus is a cluster of nerve cells located in the hypothalamus, which connects to the pituitary gland and controls the body’s endocrine system. There are several types of neurons, or nerve cells, within the structure, including those that regulate hormones including dopamine.

The arcuate nucleus, located within the hypothalamus, plays a critical role in the neuroendocrine system and is linked to the hypothalamic-hypophyseal portal system. This specialized vascular arrangement comprises a network of capillaries designed to efficiently transport hormones from the hypothalamus to the anterior pituitary gland.

The arcuate nucleus is probably the best characterized hypothalamic nucleus involved in the control of energy balance. Specifically, pro-opiomelanocortin (POMC) neurons and agouti related protein (AgRP) neurons that reside within the arcuate nucleus are required for regulating energy homeostasis, food intake, and glucose homeostasis.

In the medulla oblongata, the arcuate nucleus is a group of neurons located on the anterior surface of the medullary pyramids. These nuclei are the extension of the pontine nuclei.
