Question

Quizplus · Accepted Answer

The middle ear is an air-filled space within the temporal bone that contains the ossicles, which transmit sound vibrations from the eardrum to the inner ear.

Answer: A
 The eardrum, or tympanic membrane, is located at the boundary between the outer and middle ear, where it receives sound waves and converts them into vibrations.

Answer: C
 The pinna (also called the auricle) and external auditory meatus (ear canal) are part of the outer ear, which collects and directs sound waves toward the eardrum.

Answer: D
 The fleshy portion of the external ear is also known as the pinna (or auricle), and it helps to capture sound waves and funnel them into the ear canal.

Answer: B
 The organ of hearing is the cochlea, which is located in the inner ear. The middle ear serves to amplify and transmit sound vibrations to the cochlea.
