Top Ten Human Senses

Science tells us that humans only have five senses---sight, smell, hearing, taste, and touch. But is this true? In fact, the claim that humans are limited to five senses is a myth. We actually have many more, and this list ranks them on their impact on how we live our lives and the interesting ways they operate.
The Top Ten
Sight Sight, also known as vision, is the ability to detect light and interpret it as visual images. It is mediated by the eyes and involves the retina and the optic nerve. This sense allows organisms to perceive shapes, colors, and spatial orientation.

Seeing is not necessarily vital to human life, but it definitely makes everything a lot easier. Touch can sense texture, hearing can sense tone, smell can sense aroma, and taste can sense flavor. Sight can perceive all of these things, plus two more that are very powerful - color and dimension.

I'd be okay with everything else being taken away except my sight. I just need to be able to draw, and I'm set for life.

I just won't be able to do much if I get really hurt and will have to give up the pleasures of pizza.

Sight is probably my favorite sense because without it, I can't read. I mean, I know there are Braille books, but I also write. I just love seeing words on pages.

Touch Touch, or tactile perception, is the sense of physical contact with surfaces and textures. It is facilitated by specialized receptors in the skin and other tissues. This sense helps organisms detect pressure, vibration, and texture.

Many people may not realize it, but touch is an extremely vital sense for humans. Imagine not being able to physically feel anything. It would be the most confusing and frustrating experience. Touch actually helps our sense of sight because it helps our body recognize and categorize objects by how they feel.

Nociception Nociception is the sensory process of detecting pain stimuli. It involves specialized nerve fibers that respond to damaging or potentially damaging conditions. This sense triggers protective reflexes and informs the organism of harm.

Nociception is definitely an underrated sense, like many others on this list. To define this sense in one word - pain. Nociception is an interesting sense because of the research done on it. Scientists and researchers used to believe that it was just a variation of touch. However, it has since been discovered that it uses completely different sensory pathways to operate.

Hearing Hearing is the sense that detects sound vibrations through the ear. It involves the conversion of air pressure waves into neural signals by the auditory system. This allows for the perception of pitch, volume, and direction of sound.

Not many people actually pay attention to and understand how humans can hear things. I'm sure most people already know this, but for those who don't, sound is picked up by our ears as vibrations. These vibrations are processed by our ear canals, eardrums, the cochlea, and more. Hearing is a fascinating bodily function, and it would be hard to live without it.

Equilibrioception Equilibrioception, or balance, is the sense that helps maintain posture and spatial orientation. It is primarily mediated by the vestibular system in the inner ear. This sense detects changes in motion and head position.

Balance. Everybody forgot about balance, otherwise known as equilibrioception. It is strange that equilibrioception was left out of the original five senses, as it is so well-known and immensely different from any other sense. Balance gives us the ability to stand and walk around. In fact, without balance, we wouldn't even be able to tell what is up and what is down.

Proprioception Proprioception, often called "body awareness," is the sense of the relative position and movement of body parts. It relies on sensory feedback from muscles, tendons, and joints. This sense enables coordination and the execution of precise movements.

Proprioception is the sense of body awareness, meaning it allows you to tell where your body parts are positioned in relation to the rest of your body. This sense, which is very different from touch, allows us to perform complicated physical activities, such as playing sports. If you have ever been drunk, you have probably experienced a loss of this sense, as intoxication makes it harder to identify how your body is positioned.

Smell Smell, or olfaction, is the ability to detect and identify airborne chemical molecules. It is mediated by receptors in the nasal cavity that send signals to the brain's olfactory bulb. This sense plays a key role in detecting food, hazards, and environmental conditions.

Smell not only allows people to be comforted by pleasant aromas, but it also helps other senses operate. I'm sure you have heard the statement that smell is a big part of taste. Smell can also enhance your sight by providing insight into how things appear based on their scent.

Taste Taste, or gustation, is the ability to detect and identify dissolved chemical compounds through taste buds. It primarily senses sweet, sour, salty, bitter, and umami flavors. This sense is closely linked to smell in perceiving food.

Taste is often viewed as an unimportant sense because one can still satisfy their hunger even if they can't taste the food they are eating. However, having everything you consume be completely tasteless is easier said than done. Good tastes and flavors provide nourishment and pleasure, and you would never be able to experience that without taste. It would make eating and drinking very frustrating.

Thermoception Thermoception is the sense of detecting temperature changes. It involves specialized receptors in the skin and other tissues for heat and cold. This sense helps organisms respond to environmental thermal conditions.

Thermoception, the sense of how hot or cold it is, is a lot more useful than it appears to be. Many people might think that living without thermoception would make life easier because it would always seem temperate. However, lacking thermoception would make it impossible to live safely and healthily. Extreme temperatures don't just make you uncomfortably warm or cold. They can also drastically affect your internal and external health.

Temporal Perception Temporal perception is the sense of time and its passage. It involves the brain's integration of sensory and cognitive inputs to estimate duration and sequences. This sense helps organisms anticipate and coordinate actions over time.

Temporal perception is a human's perception of time without actually having to look at a clock. Everybody is familiar with the phenomenon where time seems to fly when you're having fun, but drags when you're bored. This is your temporal perception at work.
