Why do you feel the spins after using cocaine?

Answer 1

To understand why, you must understand the human vestibular system, this is a small structure in your inner ear that helps you to maintain balance. The vestibular system is composed of three semi-circular canals. The semicircular canals are interconnected tubes located inside each ear. The purpose of the canals are to tell your brain if your head is turning or rotating from rest. It is able to do this since the canals are filled with a fluid called endolymph and contains a motion sensor with little hairs (cilia) whose ends are embedded in a gelatinous structure called the cupula. As the skull twists in any direction, the endolymph is thrown into different sections of the canals, due to the resting inertia of the endolymph. The cilia detect when the endolymph rushes past, and a signal is then sent to the brain. The spinning dizzy feeling you get from spinning horizontally involves the horizontal canal, and it is aligned roughly horizontally in the head. The horizontal canal detects horizontal head movements (such as when doing a pirouette). When you being to spin, the endolymph rushes past and you are told your head is turning. However, when you spin for an extended period of time at a constant rotational velocity, the endolymph has time to equilibriate in the semicircular canal and hence no longer pushes against the cilia, causing your brain to think your head has stopped spinning. The instant you stop, the endolymph, normally travelling in a circle in the semicircular canal but because you were spinning as well, was unable to detect the spin, rushes in the opposing direction as inertia from the initially moving endolymph is forced to a stop. This triggers the cilia and causes your brain to suddenly start thinking your head is spinning in the opposing direction despite the fact it is not.

Answer 2

The fluid in your ear spins around when you spin, so when you stop, the fluid still spins. So you feel like you're still spinning after you stop. That causes you to feel dizzy. Hope this helps! :)

Answer 3

because in your ear their is a liquid and so when u stop spinning the liquid stil spins so u are dizzy..... people say by holding your ears it stops you being dizzy but i am not sure so try it your self or with a friend

Answer 4

When you spin around, the blood in your ears is spinning around, and when you stop, it still is, so you get dizzy. If you spin fast and get slower and slower until you stop, then you will only feel a teeny bit funny.

Answer 5

You still feel dizzy after you have stopped spinning because of the fluid in the semicircular canals of your ears. The fluid continues to move even after rotational stimuli cease and this causes the hairs that line each canal to continue to send messages to the brain that you are spinning. This also accounts for the falling sensation that a person often feels after tilting his/her head while spinning.

Answer 6

In you're ear there is a liquid. When you spin the liquid starts to spin, when you stop the liquid is still moving so it feels like you're still spinning when you stop.

Answer 7

There is an ear fluid which moves around when you spin and that makes your brain dizzy.

Answer 8

The fluids in your ears start to move very fast and that makes you dizzy. Hold on to something that doesn't move to keep them from moving and you will become un-dizzy. (Is that a word?)

Answer 9

It's because when u hit it, it gets in your brain cells and cut off connection between your cerebellum and medulla oblongata that's why u feel like the world is spinning in your head.
