Sense organ: An Introduction
Our senses are the physical means by which all living things see, hear, smell and touch (feel).Human beings get all of their knowledge from their senses. That is why our senses are so important.
Types of Sense Organs
Human beings have five sense organs, that enable them to perceive the information of their environment in the following manner:

A sense by which the body perceives contact with substances. in humans touch is perceived by the nerve endings in the skin. this sense in broader terms helps the humans to feel the basics/features of infinite objects present in our surroundings.
