POV: The Room Keeps Spinning. Sources- PMID 27726156 jwalkwalk00 on TT The otoconia are tiny calcium carbonate crystals that play a crucial role in maintaining your balance and spatial awareness. Under normal conditions, these microscopic crystals rest atop a gel-like bed inside the ear's gravity sensors, where they help your brain sense gravity, head tilts, and straight-line movements like moving in an elevator. By adding weight to the inner ear membranes, they allow you to feel which way is up without needing to rely entirely on your vision. Benign Paroxysmal Positional Vertigo, or BPPV, occurs when these crystals become dislodged from their normal resting spot due to aging, head trauma, or inner ear inflammation. Once loose, the otoconia drift into the fluid-filled semicircular canals, which are responsible for detecting head rotation. When you change head positions, the migrating crystals roll through these sensitive canals and push against the movement sensors, sending conflicting signals to your brain that create a sudden, intense sensation of spinning or vertigo. #dizzy #dizziness #vertigo
