How do you Use Your 5 senses?
Learn how the eyes, ears, nose, tongue, and skin translate stimuli into signals for the brain. See diagrams and videos of the anatomy and function of each sense organ.
- Sight. This technically is two senses given the two distinct types of receptors present, one for color (cones) and one for brightness (rods).
- Taste. You can argue this one should count for five senses by itself due to the differing types of taste receptors: sweet, salty, sour, bitter, and umami).
- Touch. Touch has been found to be distinct from pressure, temperature, pain, and even itch sensors.
- Pressure. Obvious sense is obvious.
- Touch. Touch is thought to be the first sense that humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin.
- Sight. Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil.
- Hearing. This sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal.
- Smell. Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the "smelling" part of the brain, the olfactory bulb and fossa.

- Taste. Taste, also known as gustation, is the ability to detect chemicals in food, minerals and dangerous substances such as poisons. This detection is performed by sensory organs on the tongue called taste buds.
- Smell. The sense of smell, or olfaction, is closely related to the sense of taste. Chemicals from food or floating in the air are sensed by olfactory receptors in the nose.
- Touch. Touch or somatosensory perception is perceived by activation in neural receptors in the skin. The main sensation comes from pressure applied to these receptors, called mechanoreceptors.
- Hearing. Hearing, also called audition, is the perception of sound. Sound is comprised of vibrations that are perceived by organs inside the ear through mechanoreceptors.
- Touch. Your skin is the largest organ in the body and is also the primary sensory organ for your sense of touch. The scientific term for touch is mechanoreception.
- Taste. Speaking of food and drink, try to keep your mouth from watering during the discussion of the next sense. Taste (or gustation) allows your brain to receive information about the food you eat.
- Sight. The third sense is sight (also known as vision), and is created by your brain and a pair of sensory organs—your eyes. Vision is often thought of as the strongest of the senses.
- Hearing. The scientific term for hearing is audition. But this kind of audition shouldn’t make you nervous. Hearing is a powerful sense. And one that can bring joy or keep you out of danger.
