The somatosensory division of the peripheral nervous system is responsible for receiving inputs like temperature, texture, smell, and taste.

The brain sends messages and commands back to the rest of the body through the spinal division of the peripheral nervous system.

Explain what happens in the nervous system when you touch a hot pan in the kitchen. Your explanation should begin with the perception of temperature, and end with pulling away your hand.
When you touched the hot pan, you immediately dropped the hot object without thinking. The response you got was that when you touched the hot pan, it signaled your muscles to let go of it. It is a simple reflex arc. The receptors in the skin, fire an action potential, which travels to the spinal cord, and triggers an action potential, which withdraw the hand.
