Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
The hypothalamus functions as a type of thermostat for the body. [36] It sets a desired body temperature, and stimulates either heat production and retention to raise the blood temperature to a higher setting or sweating and vasodilation to cool the blood to a lower temperature.
Through analyzing genetic expression of Clock genes in wild-type and knockout strains, as well as analyzing the activity of neurons within the SCN and connections to proximate nuclei of the hypothalamus in the aforementioned conditions, it has been shown that the SCN is the center of control for circadian body temperature rhythm. [19]
[18] [19] The physiological control of the body's core temperature takes place primarily through the hypothalamus, which assumes the role as the body's "thermostat". [20] This organ possesses control mechanisms as well as key temperature sensors, which are connected to nerve cells called thermoreceptors. [ 21 ]
The anterior hypothalamic nucleus is a nucleus of the hypothalamus. Its function is thermoregulation (cooling) of the body. Damage or destruction of this nucleus causes hyperthermia. The anterior hypothalamus plays a role in regulating sleep. [1] The anterior hypothalamic region is sometimes grouped with the preoptic area. [2]
Neurons from the pre-optic and hypothalamic regions of the brain that respond to small changes in temperature have also been described, providing information on core temperature. The hypothalamus is involved in thermoregulation, the thermoreceptors allowing feed-forward responses to a predicted change in core body temperature in response to ...
How to Reset Female Hormones For Weight Loss. This article was reviewed by Craig Primack, MD, FACP, FAAP, MFOMA. Hormones can be helpful heroes, supporting the immune system and a healthy sleep ...
This is one of the effectors in the homeostatic control of body temperature, and therefore highly variable in rough proportion to the heat load that threatens to destabilize the body's core temperature, for which there is a sensor in the hypothalamus of the brain. [citation needed]
