don'tyou think that, we've a sense organ to sense gravity?

Question

our ear can balence our body. can it be said as the sixth sense to sense out gravity too?'cause,we can feel a varying gravity on jumping,falling etc..

Answer 1

The sense of gravity and/or orientation of the body in space, is centered in the inner ear. There are three loops at different angles, coming out of the cochlea (snail-shell shaped). There is fluid in these loops (called, oddly enough, the 'semi-circular canals'. Inside the loops are also tiny hairs, which have nerves underneath them in the skin. As the head/body moves in space, the fluid moves in the semi-circular canals, and the varying pressure on the hairs is then interpreted by the brain. One of the reasons for motion-sickness, is that the eye doesn't have a 'fixed horizon' line, with which to orient itself.

I never thought of it as a 'sense', but you could probably say it is a type of sense. Observe how cats can almost always right themselves in space, if they fall.

Answer 2

The human anatomy is well known to doctors and biologists. There aren't any hidden organs.

The ear example you gave is probably the closest you'll get. Other than that, you can just account for the organs in your body actually moving inside of you. Your nerves are really all you need to be able to detect a change in motion.

Answer 3

I wouldn't say it would be a "sense organ", unless you relate the feeling of gravity to the sense of touch. Or, as you have said the sense of hearing very well could be a prominent factor on this issue.

Answer 4

That's not a bad way to look at it. Our inner ears have different parts to process different input. The section that senses gravity, is actually the part that gives us balance. It's a mass of crystal/hairs/ and nerves. when we tilt, the crystals gather in one area. The tiny hairs and nerves sense this and tell our brains "we're tilting". In the absence of gravity, this mechanism becomes chaotic. Resulting in the "star whoops" makin one up-chuck. Normal perception of up and down is distorted.

Answer 5

In our ears we have balance calculators. They help us to maintain the body balance & if they are disturbed we start feeling nausea, dizziness etc. Like some people suffer from sea sickness, air sickness or travelling in hilly areas.

Answer 6

i think of soul, which translated from a notice meaning breath, shows how centers of what's mandatory existence has replaced over the a protracted time. In Greek circumstances, even vegetables had souls on account that they too shared the breath of existence. Now that we define dying and existence in terms of the innovations, the soul or essence of existence has shifted to the innovations. i think of of the term soul as what ever it is that ends at dying. on account that we now define dying as innovations dying, we expect of of it because of the fact the tip of innovations interest. yet as you element out, it particularly is all the failings which deliver us and shop us in existence. i be attentive to no longer something approximately ghosts and function a tendency to be a skeptic approximately such comments.

Answer 7

balance IS the gravity sense in our bodies- the effects on astronauts in free fall are evidence of that- most of those who have been in space have had cases of motion sickness (from mild to nasty).

Answer 8

Its not a sense organ, but our brain does sense it

Answer 9

We have. The gravitational point lies on center of legs. If changes from them , if feel

Answer 10

no, it is just the nerves in our organs felling that they are slightly out of place when we fall.
