TOUCH

Touch is our part:

When you feel something you use the sense of touch.

From head to toe you feel the sense of touch through the entire  surface of your skin.

The skin has many layers the inner layer is called dermis, dermis has millions of nerve endings.

Touch is 4 sensations:

-HOT

-COLD

-PAIN 

-PRESSURE

Not all the body parts are equally sensitive for example, your fingertipts face and lips have more nerve endings.
