Amazing Facts About Human Sense Organs

0

Human beings can never experience life without their five senses. They are the smell and the sight of red roses in a garden through our eyes and nose, the chirping of singing birds through our ears, the taste of a pizza through our tongue and the soothing touch from someone we love through our skin. The input from the 5 senses is carried from neurons (special nerve cells) to the human brain.

Our sense organs give us the ability to understand and appreciate the surrounding and our beautiful world on five different levels and beyond. The sense organs help us to learn, to protect ourselves and to enjoy our world. Some amazing facts about our 5 senses i.e. taste, sight, touch, smell, and hearing are given below.
