Sense organ
Extracted from the Wikipedia article Sense.
A sense is a biological system used by an organism for sensation, the process of gathering information about the surroundings through the detection of stimuli. During sensation, sense organs collect various stimuli (such as a sound or smell) for transduction, meaning transformation into a form that can be understood by the brain. Sensation and perception are fundamental to nearly every aspect of an organism's cognition, behavior and thought.
