According to audiometry data a patient has a disturbed perception of medium-frequency sounds. It might have been caused by a damage of:
- A. Middle part of helix
- B. Lateral geniculate bodies
- C. Cochlear nuclei
- D. Spiral ganglion
- E. Quadritubercular structure
Hint
Frequency is mapped along the length of the cochlea (tonotopy), so think of where along the spiral the receptor cells for mid-range pitch lie.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
