WebbMoreover, thermoreceptors help us to sense heat and cold temperatures. These receptors are responsible for the sensation of “goosebumps” when we feel cold. Evolutionarily, goosebumps form to pull hair upright and increase body temperature by trapping heat closer to the skin. This is especially evident for animals with thick fur. WebbThermoreceptors in the skin detect changes in skin temperature outside the normal range and send nerve impulses to the hypothalamus. The skin is also part of the body’s response to excessive hot or cold. Let’s look at components of the skin that are useful in regulating the heat of the body. Want to keep learning?
