Differences in temperature in the skin are detected by so-called thermoreceptors, a type of nerve endings that branch profusely in the dermis and epidermis. These receptors, which detect temperature differences of only 0.001º, are of two types: those for cold, which abound on the lips , nose , chin , chest and fingers ; and those of the heat, that concentrate in the tips of the fingers, the elbows and the nose. However, the most sensitive thermal receptors are found in the brain, since it requires a stable temperature of 37ºC – and never higher than 40.5ºC – for it to function optimally.
What parts of the human body suffer the most from the cold?
