Sensory organs are very highly developed and specialized organs that are an extension of the central nervous system, with a sole function to take in information and relate it to the brain. The sensory neurons are highly adapted to detect changes of both external and internal changes in the environment and report these changes to the brain. Whether through touch, sound, taste, sight, or smell, the senses are constantly reporting variances, nuances, and dramatic changes within the environment to the brain. This is done through nerve actions, or action potentials.
A stimulus, through any nerve pattern, is sensed and must be interpreted by the brain in an uninterrupted flow in order for the sense to become real for the body. The sensory system supplies the body with pleasurable sensation as well as warning the body to dangers, such as the sensation of heat, the sounds which warn, and the smell of toxic chemicals, smoke, or other alerting odors. This combination of stimuli makes the sensory system on of the most complex in the human body.
