What structure in the external ear is responsible for funneling sound toward the middle ear?

• A. Auditory canal
• B. Auricle
• C. Tympanic membrane
• D. Stapes

Answer: (B)

The auricle, also known as the pinna, is the visible part of the outer ear that plays a crucial role in the process of hearing by capturing sound waves from the environment. Its unique shape, featuring curves and contours, is designed specifically to collect and direct sound waves into the auditory canal, effectively funneling them toward the middle ear. This assists in enhancing sound detection, particularly for sounds coming from the front, where the ear's structure is optimally positioned. The other structures listed are important in the process of hearing but serve different functions. The auditory canal, while involved in transmitting sound waves to the eardrum, does not have the same funneling capability as the auricle. The tympanic membrane (eardrum) is responsible for vibrating in response to sound waves, and the stapes is a tiny bone in the middle ear that transmits vibrations to the inner ear. While all these components work together in the hearing process, it is the auricle that primarily focuses on capturing and channeling sound waves effectively.
