The five main human senses are sight, hearing, touch, taste and smell. They help us navigate our everyday life and alert us to dangers in our surroundings. Each sense is connected to a specific part of our body. For example, the outer ear includes the tympanic membrane, or eardrum, which vibrates when pressure differences occur due to sound waves. This signal is transmitted to the brain through the spinal cord. In addition, we have twenty different types of nerve endings. These help us determine pain and temperature. When the body is hurt, the nerve endings tell the brain.
