Auditory Tube

Also known as the Eustachian tube, it connects the middle ear to the nasopharynx, helping to equalize pressure in the middle ear.

External Acoustic Meatus

The ear canal, a passage leading from the outer ear to the eardrum.

Tympanic Membrane

Also known as the eardrum, a thin membrane that separates the outer ear from the middle ear and vibrates in response to sound waves.

Pinna

The visible part of the ear that is outside the head, its primary function is to capture sound waves and funnel them into the ear canal.
