What term refers to the bowl of the ear that leads directly into the external auditory canal?

• A. Concha
• B. Lobe
• C. Triangular fossa
• D. Intertragal notch

Answer: (A)

The term that refers to the bowl of the ear leading directly into the external auditory canal is the concha. The concha is the shallow depression or cavity of the outer ear, which serves to funnel sound waves into the external auditory canal. Its shape and position contribute to the overall ability to collect sounds from the environment and direct them toward the eardrum, making it an essential component of hearing anatomy. The other terms listed refer to different parts of the ear's anatomy. The lobe, for instance, generally refers to the fleshy, lower part of the outer ear and does not have a direct role in sound direction. The triangular fossa describes a different area of the outer ear, situated between the helix and antihelix, and the intertragal notch is the small indentation located between the tragus and the antitragus of the ear. None of these structures fulfill the same function as the concha in guiding sound into the auditory canal.
