#inner ear

• Dizziness — An unpleasant sensation of unsteadiness, bodily instability, or the surrounding space spinning, frequently associated with vertigo, lightheadedness, or syncope. This structural symptom can be triggered by inner ear disorders, blood pressure fluctuations, febrile states, severe dehydration, anemia, chronic fatigue, hormonal shifts (such as during pregnancy or menopause), or psychological factors like panic attacks and severe anxiety.
• Ampullae — An adapted plural form or old variant for ampullae / ampullate structures; in biology and comparative anatomy, it designates the sac-like structures, vascular dilations, or small muscular bulbs found within the semicircular canals of the inner ear or in the water-vascular system of echinoderms. Alternatively, in some old regional dialects, it represents a popular verb form derived from 'a ampula' (to bulge or structurally inflate).
