○ eustachian tube; cochlea

○ incus; stapes

1. the medical term for a fungal infection of the ear is:

○ otopyorrhea
○ otosclerosis
○ otomycosis

Explanation:

Question 96

To solve this, we recall the functions of ear structures: The cochlea is part of the inner ear and is responsible for hearing (translating sound vibrations to neural signals). The labyrinth (vestibular system) in the inner ear is responsible for balance. Let's analyze each option:

• "labyrinth; malleus": Labyrinth is for balance, malleus is a middle - ear bone for sound transmission, so incorrect.
• "eustachian tube; cochlea": Eustachian tube equalizes pressure, cochlea is for hearing, so incorrect (second part wrong).
• "cochlea; labyrinth": Cochlea for hearing, labyrinth for balance, this matches.
• "incus; stapes": Both are middle - ear bones for sound transmission, incorrect.

We analyze the medical terms:

• "tympanitis": Inflammation of the eardrum (tympanic membrane), not a fungal infection.
• "otopyorrhea": Purulent (pus - containing) discharge from the ear, not fungal.
• "otosclerosis": Abnormal bone growth in the middle ear affecting hearing, not fungal.
• "otomycosis": "Oto - " refers to ear, "mycosis" refers to fungal infection. So this is a fungal infection of the ear.

Answer:

C. cochlea; labyrinth
