WebbIn mammals, temperature receptors innervate various tissues including the skin (as cutaneous receptors), cornea and bladder. Neurons from the pre-optic and hypothalamic regions of the brain that respond to small changes in temperature have also been described, providing information on core temperature. A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range. In the mammalian peripheral nervous system, warmth receptors are thought to be unmyelinated … Visa mer In humans, along the axons of Lissauer's tract temperature or pressure sensations enter the spinal cord. The Lissauer's tract will synapse on first-order neurons in grey matter of the dorsal horn, one or two vertebral levels up. … Visa mer Thermoreceptors have been classically described as having 'free' non-specialized endings; the mechanism of activation in response to temperature changes is not completely understood. Visa mer Warm and cold receptors play a part in sensing innocuous environmental temperature. Temperatures likely to damage an organism are sensed by sub-categories of nociceptors that may respond to noxious cold, noxious heat or more than one noxious stimulus … Visa mer Cold-sensitive thermoreceptors give rise to the sensations of cooling, cold and freshness. In the cornea cold receptors are thought to respond with an increase in firing rate to cooling produced by evaporation of lacrimal fluid 'tears' and thereby to elicit a … Visa mer This area of research has recently received considerable attention with the identification and cloning of the Transient Receptor Potential (TRP) family of proteins. The transduction of temperature in cold receptors is mediated in part by the TRPM8 channel. This … Visa mer
