Sense Organs
The nervous system must receive, accept, and processes information about the world outside in order to react, communicate, and keep the body safe and healthy. Much of this information comes by way of the sensory organs: the eyes, nose, ears, tongue, and skin. Specialized cells and tissues within these organs obtain raw stimuli and translate them into signals the nervous system can use. Nerves communicate the signals to the brain, which interprets them as sight (vision), sound (hearing), smell (olfaction), taste (gustation), and touch (tactile perception).
- In order to process, the eyes translate light into image signals for the brain.
- The ear uses bones and fluid to convert sound waves into sound signals.
- Exclusive receptors in the skin send touch signals to the brain.
- Chemicals present in the air stimulate signals the brain interprets as smells.
- The tongue is the chief organ of gustation.
