It's basically a way of sucking up to someone and it's almost as annoying and shallow as when girls post shit like omg stop being so perf! and then of course the required response is no that's you bb ð and it goes back and forth like that.
Temperature receptors. The sensory system involved in perceiving the changes in skin temperature begins with free nerve endings found in the dermal and epidermal layers of skin that can be functionally classified as cold and warm thermoreceptors.
They function by sending signals to the central nervous system when their membranes are displaced. These can be further grouped into three smaller categories by what causes their signal transmissions: position and velocity receptors, velocity receptors and transient receptors. Thermoreceptors detect temperature within and outside of the body. Externally, warm receptors and cold receptors detect temperature increases and decreases within the range of 59 to 109 degrees Fahrenheit. Nociceptors recognize pain associated with extreme mechanical, temperature and chemical stimulation.
