In the West, the human body's senses are divided into eight: visual, auditory, gustatory, olfactory, cutaneous, kinesthetic, vestibular, organic. The ways in which these senses are divided from one another in concept, and combined in varying ratios in perceiving the world, differs based on individual physiology, social and cultural context, and physical surroundings. The whole sensory system, including both physical sensation and interpretation (or cognition) of information from the senses, is referred to as a sensorium.
