🧠 Nervous System🟢 BasicHypothalamus

The Hypothalamus

A small region at the base of the brain that links the nervous and endocrine systems and keeps the body's internal conditions stable.

Key points

It is the master controller of homeostasis, regulating temperature, hunger, thirst, the sleep-wake cycle and the stress response.
It controls the anterior pituitary through releasing and inhibiting hormones carried in the hypothalamo-hypophyseal portal blood vessels.
It makes two hormones, antidiuretic hormone and oxytocin, which pass down axons to be stored and released from the posterior pituitary.
The anterior region promotes heat loss and the posterior region promotes heat conservation, so it works as the body's thermostat.
The lateral hypothalamic area promotes feeding and the ventromedial region contributes to satiety (part of a wider network including the arcuate nucleus), while the suprachiasmatic nucleus sets the daily body clock.
It sits at the top of the hypothalamic-pituitary-adrenal axis, linking a perceived stressor to cortisol release.

The hypothalamus is the thermostat, the appetite switch, the body clock and the boss of the pituitary — homeostasis headquarters.
