WebbIn some species, thermoreceptors are also involved in food location and sexual activities. Bloodsucking insects, such as mosquitoes, are attracted by thermal (infrared) radiations of warm-blooded hosts; such snakes as pit vipers can locate warm prey at considerable distance by means of extremely sensitive infrared receptors. WebbTwo types of thermoreceptors are located in the skin. Warm receptors are free nerve endings, which are sensory neuron dendrites, in the deep dermis that are most sensitive to temperatures above 25 °C (77°F). Cold receptors are free nerve endings in the superficial dermis that are most sensitive to temperatures below 20°C (68°F). Webb6 okt. 2024 · Our sense of touch is controlled by a huge network of nerve endings and touch receptors in the skin known as the somatosensory system.
