Sensory organs are highly developed, specialized organs that are an extension of the central nervous system. The sole function of the sensory organ is to take in information and relate it to the brain.
The sensory neurons detect changes of both external and internal changes in the environment and report these changes to the brain.
The brain's interpretations of the sensations are called perception. Perception is the brain's method of determining whether the information sent to the brain is pleasurable, painful, dangerous, or joyful. These perceptions explain to the body how to respond to the stimuli. Without this communication, the sensory system is useless.
