outer ear
external auditory canal
internal auditory canal
middle ear

question 23

what connection between the ear and pharynx makes your ears pop when pressure changes?

tympanic membrane
external auditory canal
eustachian tube
internal auditory canal

Explanation:

• Question 22: The ossicles (malleus, incus, stapes) are located in the middle ear. The outer ear includes the pinna and external auditory canal. The internal auditory canal is part of the inner ear region related to nerve passage.
• Question 23: The eustachian tube connects the middle ear to the pharynx. When pressure changes (e.g., during altitude changes), it opens (usually with a "pop" sound) to equalize pressure. The tympanic membrane (eardrum) is a membrane in the middle ear. The external auditory canal is in the outer ear. The internal auditory canal is for nerve passage.

Answer:

• Question 22: middle ear
• Question 23: eustachian tube
