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 Visa mer Cold-sensitive thermoreceptors give rise to the sensations of cooling, cold and freshness. In the cornea cold receptors are thought to respond … Visa mer This area of research has recently received considerable attention with the identification and cloning of the Transient Receptor Potential (TRP) … Visa mer WebbIn most cases, a sensory receptor that is activated by enough stimuli results in graded potentials, which initiate nerve impulses along afferent fibers of the PNS. The brain can …

WebbAs a rule, each thermoreceptor is connected with a single nerve fibre. By using very finely tipped thermal stimulators, investigators can locate precisely the sites of warm and cold receptors in the skin; the details of the underlying cellular structure at these spots have been studied by electron microscopy.
