what structure is highlighted?

a. cochlea
b. vestibule of ear
c. auricle of ear
d. semicircular canals
e. tympanic membrane

Explanation:

Identify the highlighted structure

Using the Tympanic Membrane Anatomy knowledge point
The highlighted structure in green is located at the boundary between the external acoustic meatus (ear canal) and the middle ear cavity. This thin, semi-transparent membrane vibrates in response to sound waves and is anatomically known as the tympanic membrane (eardrum).

Match with the given options

Using the Tympanic Membrane Anatomy knowledge point

• Option A (Cochlea) is the snail-shaped structure of the inner ear, visible further to the right.
• Option B (Vestibule of ear) is the central part of the bony labyrinth in the inner ear.
• Option C (Auricle of ear) is the external visible part of the ear.
• Option D (Semicircular canals) are the three looped structures of the inner ear.
• Option E (Tympanic membrane) is the highlighted green structure.

Answer:

• (A) Cochlea
• (B) Vestibule of ear
• (C) Auricle of ear
• (D) Semicircular canals
• (E) Tympanic membrane (Correct answer)
