The 5 senses play a key role in one’s interaction with the world. The nervous system must receive and process information about the world outside in order to react, communicate, and keep the body healthy and safe. Much of this information comes through the sensory organs: the eyes, ears, nose, tongue, and skin. Specialized cells and tissues within these organs receive raw stimuli and translate them into signals the nervous system can use. The 5 senses are:

  • Sight: The eyes translate light into image signals for the brain to process.
  • Hearing: The ear uses bones and fluid to transform sound waves into sound signals.
  • Touch: Specialized receptors in the skin send touch signals to the brain.
  • Smell: Chemicals in the air received through the nose, stimulate signals the brain interprets as smells.
  • Taste: The tongue through its taste buds is the principal organ of taste.
