Concept: This question tests your knowledge of medical terminology related to the ear, specifically identifying the correct term for inflammation of the tympanic membrane.

Why (C) is correct: The term myringitis specifically refers to the inflammation of the tympanic membrane (eardrum). The prefix 'myring-' comes from the Greek word 'myrinx' meaning eardrum, and the suffix '-itis' denotes inflammation.

Why other options are wrong:

• (A) otalgia: This refers to earache or pain in the ear, not specifically inflammation of the tympanic membrane.
• (B) vertigo: This is a sensation of spinning or dizziness, often associated with inner ear problems, but not inflammation of the tympanic membrane itself.
• (D) eustachitis: This refers to the inflammation of the Eustachian tube, which connects the middle ear to the nasopharynx, not the tympanic membrane.

NEET Tip: Many medical terms are derived from Greek or Latin roots. Learning common prefixes and suffixes (like '-itis' for inflammation) can help you deduce the meaning of unfamiliar terms.

Correct Answer: (C)
