人和高等动物具有一套完整的体温调节装置,此调节系统的末梢(即温觉感受器),分布在皮肤和某些粘膜,当它们感受到内外环境温度变化时,即发出信息至位于下丘脑的体温调节中枢,经中枢整合后,引起骨骼肌、内分泌腺、皮肤血管等活动的变化,从而调整机体产热和散热的能 People and animals have a complete set of thermoregulatory devices. The distal end of the regulatory system (ie, the thermoreceptors) is located in the skin and certain mucosa. When they feel changes in the internal and external temperatures, they send messages to the hypothalamus Of the body temperature regulation center, the central integration, causing skeletal muscle, endocrine glands, skin blood vessels and other changes in activity, so as to adjust the body heat and heat
