Thermoregulation in the brain
Webb1 okt. 2000 · Thermoregulation In the late 1800s and early 1900s, several lesion and stimulation studies identified the rostral hypothalamus as an important neural structure in the regulation of body temperature [ 1–10 ]. The compilation of years of lesion studies suggests that no single neural area acts as the center for thermoregulation [ 11–13 ]. WebbIn thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to …

WebbHow does this work? First, high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing … Webb1 sep. 2015 · Thermoregulation is the maintenance of a relatively constant core body temperature. Humans normally maintain a body temperature at 37°C, and maintenance of this relatively high temperature is critical to human survival. This concept is so important that control of thermoregulation is often the principal example cited when teaching …
