What happens in the body when you eat something cold?
Thermoreceptors in the nerve cells of the mouth respond to temperature of objects. When these receptors are activated, ion channels are opened and action potentials are sent to the central nervous system. Cool objects/food activates these thermoreceptors. However, if something that is too cold enters the mouth, nociceptors will be activated. These receptors register pain and inform the central nervous system that the object is harmful.

Where in the human body are the only nerves that continually regenerate?
The only nerves in the human body that continually regenerate are found in the Peripheral Nervous System (PNS). This allows for limited repair and regeneration of damaged nerves in the PNS.
