Hypothalamus

Hypothalamus

(Science: anatomy, endocrinology) a portion of the brain which lies beneath the thalamus and secretes substances which control metabolism by exerting an influence on pituitary gland function.

The hypothalamus is also involved in the regulation of body temperature, water balance, blood sugar and fat metabolism. The hypothalamus also regulates other glands such as the ovaries, parathyroids and thyroid. A basal part of the diencephalon governing autonomic nervous system.A section of the brain that is involved in many regulatory functions like osmoregulation and thermoregulation. The hypothalamus has a degree of control over the pituitary gland, and also controls sleeping patterns, eating and drinking and speech. It is also responsible for the secretion of adh (Anti-Diuretic Hormone) via its neurosecretory cells.

Homeostasis in Humans

The body temperature is controlled by the anterior hypothalamus (the preoptic area). It directly senses the temperature, as well as evaluates the thermoreceptor signals coming from the skin and other parts of the body (e.g. mucous membranes). Based ...

Homeostasis connections

... it's really just osmoregulation to control the level of fluids/salinity, isn't it? Which is controlled by kidneys, endocrine and nervous systems (hypothalamus, I think, which controls whether we feel thirsty). Not sure how/why immune system would be involved though.
