WebbThermoregulation is coordinated by the nervous system (Figure 11.2). The processes of temperature control are centered in the hypothalamus of the advanced animal brain. The hypothalamus maintains the set point for body temperature through reflexes that cause vasodilation or vasoconstriction and shivering or sweating. WebbThermoreceptors are sensory receptors which respond to heat and cold body temperature changing. They are located mainly in the skin and mucous membranes in body. Explain the negative feedback control of body temperature using thermoreceptors, the hypothalamus, and effectors. Thermoreceptors detect change from temperature set point. hrs 096-103a https://fridolph.com
