Our senses are the physical means by which all living things see, hear, smell, taste, and touch. Each sense collects informaton about the world and detects changes within the body. Both people and animals get all of their knowledge from their senses, and that is why our senses are so important.
All senses depend on the working nervous system.
Our sense organs start to work when something stimulates special nerve cells called receptors in a sense organ.
We have five main sense organs. They are the eyes, nose, ears, tongue, and skin.
Once stimulated, the receptors send nerve impulses along sensory nerves to the brain. Your brain then tells you what the stimulus is.
For example, your sound receptors would be bombarded by billions of sound waves.
When these signals reach the part of the brain called the cerebral cortex, we become conscious of the sounds. If you need to have a better overview of the nervous system,
you can check out the following sites:
Our group really learned a lot about the senses while creating this website. We hope that you are able to get just as much out of it. Please feel free to comment about anything on the site by e-mailing us. Also, don't forget to sign the guestbook! Thanks for visiting our site. Come back soon!
