Topic: Thermoreceptor


  
  Thermoreceptor - Wikipedia, the free encyclopedia
A thermoreceptor is a sensory receptor that responds to temperature, primarily within the innocuous range.
A special form of thermoreceptor is found in some snakes, the viper pit organ and this specialised structure is sensitive to energy in the infrared part of the spectrum.
Thermoreceptors have been classically described as having 'free' non-specialised endings; the mechanism of activation in response to temperature changes is not completely understood.

Thermoreceptors are means by which humans and animals receive information about their thermal environment.
A computer model based on the Hodgkin-Huxley equations was formulated to simulate thermoreceptor action.
Simulated thermoreceptors can be used as a component of larger thermal models of animals.

Abstract: Sensations of cold are mediated by specific thermoreceptor nerve endings excited by low temperature and menthol.
Here we identify a population of cold-sensitive cultured mouse trigeminal ganglion neurons with a unique set of biophysical properties.
Their impulse activity during cooling and menthol application was similar to that of cold thermoreceptor fibers in vivo.

Also, novel materials and methods are introduced for investigating the functional organization of cold sensory reception in human skin, including: (a) estimation of sensory field size for single cold-sensory fibers, (b) demonstration of the discontinuous distribution of cold-sensory fibers in skin, and (c) estimation of the density of cold-sensitive fibers per unit area of skin.
Tactile and thermoreceptor functions are related to underlying neuroanatomy of peripheral and central neural pathways.

It is supplied with nerves and blood vessels and is partially enclosed in a cavity in the side of the maxillary, a bone of the upper jaw.
The pit has a thermoreceptor function and is sensitive to infrared radiation; it is capable of responding to changes in temperature of only fractions of a degree.
Thus pit vipers can detect the presence of animals with body temperatures only slightly different from that of the environment.
