What is arkuat nükleus?

Arcuate nucleus is a group of neurons located in the hypothalamus of the brain. It is involved in regulating appetite, metabolism, and reproductive behavior. The arcuate nucleus receives inputs from hormones like leptin, ghrelin, and insulin, which control hunger, satiety, and energy expenditure. The arcuate nucleus produces and releases neuropeptides like melanocortin, neuropeptide Y, and agouti-related protein, which are involved in modulating feeding behavior. Dysregulation of the arcuate nucleus has been linked to obesity, diabetes, and other metabolic disorders.
