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 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]
The hypothalamus is highly involved in maintaining homeostasis of the body, and the median preoptic nucleus is no exception, contributing to regulation of blood composition, body temperature, and non-REM sleep. The median preoptic nucleus is highly involved in three main areas. These include osmoregulation, thermoregulation, and sleep ...
The posterior nucleus of the hypothalamus is one of the many nuclei that make up the hypothalamic region of the brain. Its functions include elevation of blood pressure, pupillary dilation, and shivering or body heat conservation (thermoregulation). [1] Damage or destruction of this nucleus causes hypothermia.
The Preoptic anterior hypothalamus (or POAH) is the part of the brain that senses core body temperature and regulates it to about 36.8 °C (98.6 °F). References [ edit ]
The hypothalamus is located below the thalamus and is part of the limbic system. [1] It forms the basal part of the diencephalon. All vertebrate brains contain a hypothalamus. [2] In humans, it is about the size of an almond. [3] The hypothalamus has the function of regulating certain metabolic processes and other activities of the autonomic ...
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
The ventromedial nucleus of the hypothalamus (VMN, VMH or ventromedial hypothalamus) is a nucleus of the hypothalamus. In 2007, Kurrasch et al . found that the ventromedial hypothalamus is a distinct morphological nucleus involved in terminating hunger, fear, thermoregulation, and sexual activity. [ 1 ]
