In physiology, thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux.It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate defense response.
Thermoreceptors of the skin sense the temperature of water. A thermoreceptor is a non-specialised sense receptor, ... causing the sensation of heat or burning.
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. ... Thermoception – Sensation and perception of temperature;
The tracts convey pain, [6] temperature (protopathic sensation), and crude touch from the periphery to the brain. The most important of these is the spinothalamic tract. The most important of these is the spinothalamic tract.
"Touch" is an objective sensation, but "pain" is an individualized sensation which varies among different people and is conditioned by memory and emotion. Anatomical differences between the pathways for touch-position perception and pain-temperature sensation help explain why pain, especially chronic pain, is difficult to manage.
For example, the temperature modality is registered after heat or cold stimulate a receptor. Some sensory modalities include: light, sound, temperature, taste, pressure, and smell. The type and location of the sensory receptor activated by the stimulus plays the primary role in coding the sensation. All sensory modalities work together to ...
Thermo-TRP channels have a C-terminal domain that is responsible for thermosensation and have a specific interchangeable region that allows them to sense temperature stimuli that is tied to ligand regulatory processes. [39] Although most TRP channels are modulated by changes in temperature, some have a crucial role in temperature sensation.
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
