Senses

How do we get information about what is happening outside our bodies? Our senses are the means by which we are able to figure this out. Each sense will collect information about the world and detect changes within the body.

Our senses depend on a working nervous system. The sense organs start to work when something stimulates their special nerve cells, known as receptors, in the sense organ. There are five sense organs:

1. Eyes - Sense of Sight,
2. Ears - Sense of Hearing,
3. Nose - Sense of Smell,
4. Tongue - Sense of Taste
5. Skin - Sense of Touch

Once stimulated, the receptors send nerve impulses along sensory nerves to the brain. Your brain will then tell you what the stimulus is and how to react to it.

Your sound receptors in the ears are bombarded with billions of sound waves. When the nerve signals reach the brain through the cerebral cortex, we become conscious of the sounds. The brain tells the body how to react to them.
