Here are some of the most interesting and surprising facts about the human body.
- The tongue has 3,000 taste buds, each with sensory nerve connected with the brain that carries impulses which the brain interprets and passes judgment.
- The ears have 100,000 auditory cells. Minute nerve ending in the inner ear picks up a particular sound frequency and start vibrating.
- Each eye has 130,000,000 light receptors which send impulses to the brain.
- The skin has a vast network of receptors. If a hot object touches the skin, some 30,000 “hot spots” will warm of the danger. It has 250,000 cold receptors and about 500,000 touch receptors. The brain pays little attention to messages sent by only a few receptors.
