question 6 (2 points) retake question
what separates the outer and middle ear?
a) tympanic membrane
b) organ of corti
c) auricle
d) auditory canal

Explanation:

The tympanic membrane (eardrum) is a thin membrane that acts as a barrier between the outer ear (external auditory canal) and the middle ear. Sound waves in the outer ear cause the tympanic membrane to vibrate, which then transmits these vibrations to the middle ear ossicles (malleus, incus, stapes). The organ of Corti is in the inner ear (in the cochlea) and is involved in auditory transduction. The auricle (pinna) is the visible part of the outer ear that helps collect sound waves. The auditory canal is part of the outer ear.

Answer:

A. Tympanic membrane
