Why Do You Feel Dizzy After Spinning?

READ THE IMAGE

What the illustration shows

Medical illustration titled “Why Do You Feel Dizzy After Spinning?” A cutaway inner ear shows three semicircular ducts, an enlarged ampulla, and vestibular nerve. Magnified views show hair-cell bundles embedded in the gelatinous cupula above a sensory ridge, with supporting cells and basal nerve fibers. Three matched panels show the mechanism: when turning starts, fluid lags relative to the duct and the cupula bends left; during sustained steady turning, relative motion fades and it returns toward upright; after stopping, relative fluid motion reverses and the cupula bends right. These temporary signals can make you feel motion after you stop. Arrows indicate qualitative fluid motion relative to the duct. AllHumanBody.com.

How to interpret this poster

• A qualitative response after sustained rotation is shown, not an exact time course or a complete explanation of dizziness.
• The posterior duct is partly hidden; the image is not a complete three-dimensional labyrinth map.
• Arrows describe motion relative to the duct, not measured flow speeds.
• AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
• Fine annotations need enlargement; the full description provides an accessible text alternative.
