Serena is on an airplane that has just taken off. Suddenly see feels pressure in her ears and her ears seem “clogged". Which structure in her ear needs to equalize the pressure between her middle ear and nasopharynx?

A	tympanic membrane
B	ossicles
C	organ of corti
D	eustachian tube

Explanation:

Detailed explanation-1: -Airplane ear occurs when the air pressure in the middle ear and the air pressure in the environment don’t match, preventing your eardrum (tympanic membrane) from vibrating normally. A narrow passage called the eustachian tube, which is connected to the middle ear, regulates air pressure.

Detailed explanation-2: -Ear pressure can occur due to sinus congestion, infections, or TMJ damage, among other conditions. It can also occur as a result of situational factors, such as changes in altitude or having a foreign body stuck inside the ear. Some causes of ear pressure are treatable using OTC medications and home remedies.

Detailed explanation-3: -The primary function of the Eustachian tube is to equalize air pressure between the atmosphere and the middle ear. Yawning and swallowing cause contraction of the muscles connected to the Eustachian tube, enabling the tube to open to small amounts of air.
