thermoreceptor

[¦thər·mō·ri′sep·tər]
(physiology)
A sense receptor that responds to stimulation by heat and cold.

Thermoreceptor

 

a nerve ending found in various tissues and organs whose specific function is to react to changes in body temperature by changing the frequency of bioelectric impulses. Thermoreceptors send appropriate signals to the thermoregulatory center. The skin contains both cold and heat receptors. Cold receptors show a maximum frequency of 9–12 impulses per sec when the skin temperature is between 25°C and 30°C, and heat receptors show a maximum frequency of 30–40 impulses per sec when the skin temperature is between 42°C and 45°C. Temperature sensations are produced by the combined excitation of both types of thermoreceptors.

A similar discussion of transient responses of thermal sensations and thermoreceptor responses can be found in the literature (Gagge et al.

Such modality interconversions are reasonable because chemoreceptors and thermoreceptors in nematodes utilize the same classes of intracellular signaling molecules and transcription factors as animal photoreceptors (Svendsen and McGhee, 1995; Coburn and Bargmann, 1996; Mori, 1999; Troemel, 1999; Komatsu et al., 1999; Satterlee et al., 2001; Arendt, 2003; Kimura et al., 2004; Inada et al., 2006).
It is difficult to understand why a thermoreceptor would be moved 100 [micro]m posteriorly in M.
The hypothalamus, upon receiving input from peripheral thermoreceptors located in the skin and central thermoreceptors sensitive to blood temperature located in the body core (the organs within the skull and the thoracic and abdominal cavities), responds like a thermostat to this input by reflexively initiating appropriate heat-promoting or heat-loss activities via autonomic pathways, allowing the hypothalamus to anticipate changes of the core temperature (Marieb 2004).

Thermosensitivity in lobsters may be mediated by distinct thermoreceptors or thermosensitive neurons as in some other invertebrates (Prosser and Nelson, 1981; Mon and Ohshima, 1995).
However, the actual thermoreceptors have not been identified in these species.
