Question

a child may sometimes play by quickly turning around in a circle. when the child stops, he or she often feels like his or her head is still spinning. what is responsible for this sensation?
disruption of the otolith crystals
fluid still rotating in the semicircular canals
compression of the otolith organs
proprioceptors

Explanation:

The semicircular canals in the inner - ear contain fluid. When a child spins and then stops, the fluid in these canals continues to move due to inertia, sending false signals to the brain about the head's position, causing the spinning sensation. Otolith crystals and organs are related to linear acceleration and gravity - sensing, and proprioceptors are related to body position but not this spinning - related dizziness.

Answer:

fluid still rotating in the semicircular canals
