Question

When you bend your head to the right, the fluid moves _______?

1) upwards
2) downwards
3) sideways
4) cannot be determined

Answer 1

When bending your head to the right, the fluid in the semicircular canals moves horizontally to the left, aiding in the transmission of balance information to the brain.

Step-by-step explanation:

When you bend your head to the right, the fluid inside your ear's semicircular canals moves due to the momentum, and because the fluid will move in the opposite direction to the head's movement, it moves horizontally to the left side of the coordinate system. This fluid movement bends the stereocilia within the canals and sends signals to your brain about your head's position in space, helping with balance and orientation.
