The anatomy and structure of the five sense organs of the human body: vision, hearing, smell, taste, and touch.
One categorization for human senses is as follows: chemoreception; photoreception; mechanoreception; and thermoception. This categorization has been criticized as too restrictive, however, as it does not include categories for accepted senses such as the sense of time and sense of pain. Some non-human animals possess senses that are absent in humans, such as electroreception and detection of polarized light.
