Questions: Which structure allows the air pressure in the middle ear to be equalized with the atmospheric pressure? - bony labyrinth - auditory tube - auricle - cochlea

Transcript text: Which structure allows the air pressu bony labyrinth auditory tube auricle cochlea

Solution

The answer is the second one (auditory tube): the original text in the question...

Explanation for each option:

Bony labyrinth: This is a complex structure in the inner ear that contains the cochlea, vestibule, and semicircular canals. It does not regulate air pressure.
Auditory tube: Also known as the Eustachian tube, this structure connects the middle ear to the nasopharynx and helps equalize air pressure on both sides of the eardrum.
Auricle: This is the external part of the ear, also known as the pinna, which collects sound waves but does not regulate air pressure.
Cochlea: This is a spiral-shaped organ in the inner ear responsible for converting sound vibrations into neural signals. It does not regulate air pressure.

Summary: The structure that allows the air pressure to be equalized in the ear is the auditory tube.
