A region lying below the thalamus and above the pituitary gland that maintains homeostasis, regulating body temperature, blood water potential, hunger and circadian rhythms, and controlling pituitary secretions.
Links the nervous and endocrine systems, and with the autonomic nervous system controls hormone release, for example adrenaline from the adrenal medulla.
Contains thermoreceptors that detect blood temperature and coordinates thermoregulatory responses by sending impulses to effectors.
