Course 23 · Unit III

The Ears

Class 23. Hearing and balance. Three rooms. The chain. The duct. Corti. High and low. Canals and otoliths. Sudden hearing loss, spinning that will not stop, a draining ear: a physician. Kidney–ear is a rhyme. Implants are not a first question. The dose does not enter.
