Thermoreceptors psychology definition
WebbThermoreceptors are specialized nerve cells that have free nerve endings that locate beneath the skin. When these thermoreceptors detect a change in temperature, the information is sent via afferent neurons up the spinal cord and to the brain, more specifically the hypothalamus. After information is integrated in the. 996 Words. WebbA thermoreceptor is a non-specialized sensory cell, or more precisely the receptive portion of a sensory neuron, that reads subtle changes in temperature. In addition, there are heat receptor and cold receptor cells that register temperatures that are above or below the ambient temperature.

Supplement Snakes have special thermoreceptor s found in the pit organ involved in infrared sensing. Word origin: thermo – + receptor Compare (with other sensory receptors): Proprioceptor Webb1 sep. 2015 · When a body is warm, the air molecules that make contact with the body will be warmed, reducing their density, which causes the molecules to rise and be replaced with cooler air. Convective heat exchange is increased by movement of the body in air or water or movement of air or water across the skin.
