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.
Our somatosensory system consists of sensors in the skin and sensors in our muscles, tendons, and joints. The receptors in the skin, the so called cutaneous receptors, tell us about temperature (thermoreceptors), pressure and surface texture (mechano receptors), and pain (nociceptors). The receptors in muscles and joints provide information about muscle length, muscle tension, and joint angles.
