Processing Reality
Function:
In order to learn and interact with the word around us we use our five senses: smell, taste, sight, hearing, and touch. The nervous system must receive and process this information to react, communicate, and keep your body healthy and safe. Most 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. Nerves relay the signals to the brain, which interprets them as sight (vision), sound (hearing), smell (olfaction), taste (gustation), and touch (tactile perception)Fun Fact:
One of the earliest known forms of body modification is ear piercing.Related Handouts
