Which of these is not a sense organ?

A sense is a way in which humans can gain information about the world around them. Humans have five senses. The five senses are sight, smell, hearing, taste, and touch.

The body parts used for these senses are called sense organs. The sense organs include the eyes, nose, ears, tongue, and skin.

The sense organs do not work alone to sense the world that surrounds them. They need the help of the brain and nerves.

A nerve is a bundle of fibers that send messages between the brain or spinal cord and the body's organs. There are about ten million nerve cells in the brain.

The sense organs take in information from the environment and send it to the brain along sensory nerves.

A sensory nerve is a nerve that sends electrical messages from a sense organ to the brain. The brain processes the information and tells the body how to respond.

How do you hear things so quickly? How do you know instantly what you are seeing? Your brain sends messages at the rate of 240 miles per hour.
