Thermoreceptors in homeostasis
Webb15 apr. 2024 · Core body temperature in mammals is regulated by thermoreceptors in the hypothalamus in the brain, spinal cord, large veins, and internal organs. When the core temperature gets too high, the … WebbThe human body regulates body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different. The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F).

Rattlesnakes and pit vipers in the subfamily Crotalinae have a pair of facial pits—sense organs on the head lying below and in front of the eyes that … A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range. In the mammalian peripheral nervous system, warmth receptors are thought to be unmyelinated C-fibres (low conduction velocity), while those responding to cold have both C-fibers and thinly myelinated A delta fibers (faster conduction velocity). The adequate stimulus for …
