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.

The different types of input are sensed by a variety of mechanoreceptors, proprioceptors, nociceptors, and thermoreceptors that are responsive to changes in muscle length and rate of change in length, muscle tension, joint position, vibration, deep pressure stimulation, skin pressure, pain, temperature, and touch (Shelton, 1989).
Available in cool caplets, geltabs, and gelcaps, Allergy Complete Multisymptom additionally features a coating of CoolBurst, which uses CoolTek technology to stimulate thermoreceptors in the mouth and throat to create a cooling sensation.
The feeling of increased nasal patency may be mediated by thermoreceptors in the nasal vestibule, according to investigators Dr.
The mechanoreceptors respond to indentations of the skin; the thermoreceptors to specific temperatures and changes in temperature; and the nociceptors to intense pressure or high heat.
The hypothesis that thermoreceptors may demonstrate faster adaptations to persistent pain than mechanoreceptors is supported by evidence of thermal allodynia within 1 day of experimentally induced injury in non-primate animals, whereas mechanical allodynia either developed gradually up to 30 days after injury or was not present [22, 23].
The pulsing airflow increased the cooling effectiveness of the airflow by preventing the acclimatization of the thermoreceptors. Subjects expressed satisfaction with the airflow in all metabolic and temperature conditions.
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).
