🔬 Medical science
The ear enables hearing and balance through the outer, middle and inner ear. Common conditions include otitis media (bacterial/viral infection), noise- and age-related hearing loss, tinnitus and Ménière's disease.
Diagnosis uses otoscopy, audiometry and imaging; treatment ranges from antibiotics to hearing aids and surgery.
🧩 The GNM model
Claimed conflict: GNM links the middle ear to an "auditory morsel conflict" — not being able to grasp a piece of information one wants to hear — and inner-ear hearing to "not wanting to hear" something.
Germ layer & brain relay (GNM model): GNM classes the middle-ear mucosa as endoderm controlled from the brainstem, and the inner-ear hearing apparatus as ectoderm controlled from the cerebral cortex.
Two-phase course (claimed): GNM claims the middle-ear lining secretes/proliferates in conflict activity and that infection (otitis media with effusion) appears during the healing phase, while "not wanting to hear" conflicts are said to reduce hearing in activity.
