As Jerry nears the campfire, he is delighted at the warmth it provides. Jerry perceives this temperature because of thermoreceptors in his skin.
<h3>What are thermoreceptors?</h3>
- The receptive part of a sensory neuron, or more precisely a non-specialized sense receptor called a thermoreceptor, is responsible for coding absolute and relative changes in temperature, primarily those that fall within a safe range.
- Warmth sensors are assumed to be unmyelinated C-fibers in the mammalian peripheral nervous system (low conduction velocity), whereas cold receptors have both C-fibers and sparsely myelinated A delta fibers.
- Warm receptors respond well to warming, which causes them to discharge action potentials more quickly.
- For cold sensors, cooling causes an increase in firing rate whereas warming causes a reduction.
- A paradoxical reaction to heat is when some cold receptors react to high temperatures, usually above 45 °C, by releasing a short action potential.
