Brain Myths: Reflecting on the Impacts of Science

senses

There are many brain myths going around every time. However, do those myths really EXIST? Is is really true? I was wondering if this myth …

WE HAVE 5 SENSES.

is true or not.

First of all, why do we believe this? Where did this come from? Where did it originated? Well, we believe this myth because we were told from people that we have 5 senses. And we also learn this from our selves. We see, smell, touch/feel, hear, and taste things in our daily routine. We discovered ourselves that there are 5 senses from our daily life. So this statement is originated from us, ourselves. Humans just feels and believes it that we have 5 senses because that we don’t think further more deeply then that. But actually, there are more to think about than 5.

Well how come we care about whether if this statement is true or false?? Well, this statement matters because if this myth is true, and says that there are only 5 senses and no more then that, it doesn’t give our bodies much credits of sensations. If the senses are only 5, we can’t sense the further senses. Even you taste something sweet, if the senses are only five, you can’t explain about how it actually taste it like. You can only say, “I taste something in my mouth.” And you can’t say, “It’s sweet.” However, we often say that it’s sweet and expresses the further taste in our daily life. So from that, it means that there are further more senses than the basic 5.  In each basic 5 sensors, there each contains a several sensors, to actually have and be able to express the senses. Also, it’s a problem to believe that there are only 5 senses is because you may be missing out some important senses. I think the important senses that are not included in the basic 5 senses are the proprioception (body awareness) sense, pain sense, and the equilibrioception (maintain balance), thirst, and hunger/fullness. For instant, if you think that there are only 5 senses and you missed out the fullness sense, you won’t be able to full the fullness and you’ll end up with eating foods for ever. By this, you will more likely to be unhealthy.

Now I would like to explain some other senses that are not included in the basic 5 senses. The senses are..

  • Sight:  the color (cones) and one for brightness (rods).
  • Taste:  there are differing types of taste receptors (sweet, salty, sour, bitter, and umami), but generally is just referred to as one sense.
  • Hearing: to detect sounds.
  • Touch: allows you to feel pressure, temperature, pain, itch sensors.
  • Smell: allows you to produce flavors by conbining with many other senses.
  • Proprioception (body awareness): This sense gives you the ability to tell where your body parts are, relative to other body parts.
  • Pain:  In a word, pain.  This was once thought to simply be the result of overloading other senses, such as “touch”, but this has been found not to be the case and instead, it is its own unique sensory system.  There are three distinct types of pain receptors: cutaneous (skin), somatic (bones and joints), and visceral (body organs).
  • Equilibrioception: The sense that allows you to keep your balance and sense body movement in terms of acceleration and directional changes.  This sense also allows for perceiving gravity.
  • Thirst:  allows your body to monitor its hydration level and so your body knows when to drink.
  • Hunger:  allows your body to know when you need to eat something

From this, you can see that there are more than 5 senses to think about. Taking forward this idea, I’ll say that the myth,

WE HAVE 5 SENSES.

is NOT TRUE.
