why do you feel dizzy after spinning around fast or if your going in circles?

Question

i need the science of it. im so stuck on an assignment.

Answer 1

i don't know if u need a full scientific answer..
bt if u want some basic easy-to-remember simple explanation, i can say it this way:
when u spin, the endolymph in the semi-circular canals (in ur ears) will start to move as well, but there will be a lag in it's movement (i.e. because it is a fluid.. it try to catch on the movement of the canals). Upon this difference in speed of movement, some certain sensory hair receptor in the canals will bend (it is exactly a hair! microscopical hair!) owing to the contact with endolymph (which seems to move backwards compared to the hair cell that is attached to the canals and move faster!!). the direction of the bending of the hair defines the direction of ur movement, and the brain will know that u r spinning and in what direction..
OK.. now when u stop, the endolymph will continue to move for a while.. cos it is a liquid.. whereas the hair cell is not moving anymore, and so the endolymph will cause the sensory hair to bend in the opposite direction!!.. now the fool brain will think that u r spinning in the opposite direction.. this will last until the endolymph comes to complete stop, whcih depends on the velocity and the duration of the spinning..
i know this is long and hard. jst read it twice, and u'll never forget it!!
good luck..

Answer 2

Endolymph in semicircular canals in internal ear is responsible for maitaining posture. Fast spinning movements disturbs the fluid. Posture reflexes are disturbed. So one feels dizzy till posture and balance are regained.

Answer 3

Same for me! And about 3 minutes ago too. Then my hair's all poofy!(don't ask why!) That's my favorite thing to do! I tried to count how many times I went around, but I lost count at like, 5!

Answer 4

Look up "inner ear" or "semicircular canals". You'll find the answer.
