Question

Quizplus · Accepted Answer

The tympanic membrane, also known as the eardrum, separates the outer ear from the middle ear. It is a thin, membrane-like structure that vibrates in response to sound waves and transmits these vibrations to the three tiny bones in the middle ear. The pinna is the visible part of the outer ear, while the organ of Corti is located in the inner ear and responsible for converting sound waves into neural signals that the brain can interpret.
