Pain receptors
Sensory receptors for cold are located in the dermis, the are formally called free nerve endings.
The sensory division is what sends information from smooth muscles to the brain. The nervous system first uses sensory receptors (located everywhere internally and externally on body) to sense change (pain, cold, the need for a muscle to contract, ect.) The information gathered is sent to the brain and spinal cord by way of the sensory division.

There are many different sensory receptors, but olfactory receptors in the nose, and cones and rods in the eyes are two specific types of sensory receptors. Olfactory detects the chemical presence and your brain identifies it as a smell. The rods and cones of the eye process light and color to form images that your brain processes as vision.
