The Traditional Senses

Vision (sight): The human eyes are sense organs equipped with rods and cones. While rods help us see in low-light situations, cones are responsible for detecting colors. In fact, we have three types of cones for the three primary colors. Ever wondered why it takes a while for your eyes to adjust to the dark? It's all about the rods and cones doing their thing.
Hearing: Sound waves enter our ears and are picked up by tiny hair cells in the inner ear. These vibrations are then translated into the sounds the human brain can recognize.
Smell: The olfactory bulb in our nasal cavity processes the scents that our nose picks up. It's all about a chemical reaction happening right under your nose!
Taste: Our taste buds on the tongue have taste receptors that distinguish between different basic tastes. From sweet to salty, sensory receptors provide adventure every time we eat.
Touch: Our skin is a sensory wonderland. With nerve endings that detect heat, cold, pain, itch and pressure, our touch sense and pain receptors keep us connected to the external environment.

Beyond the Basics: Other Human Senses

Balance: Ever wondered how you can stand on one foot without toppling over? Thank the vestibular system in your inner ear. It helps us detect our orientation in the gravitational field.
Proprioception (body awareness): Close your eyes and touch your nose. You can thank proprioception for that. It's our ability to sense where our body parts are in relation to others.
Internal senses: Our internal organs, like the bladder and large intestine, have sensors too. They let us know when it's time for a bathroom break or when we're hungry or thirsty.
