Verified step by step guidance1
Step 1: Begin by identifying the anatomical structure described in the question. The outer, visible, funnel-shaped part of the ear is being referenced.
Step 2: Review the options provided: Tympanic membrane, Auricle (pinna), Cochlea, and Eustachian tube. Understand the function and location of each structure.
Step 3: Recall that the tympanic membrane is the eardrum, located deeper within the ear and not visible externally. Eliminate this option.
Step 4: Note that the cochlea is part of the inner ear and is responsible for converting sound waves into neural signals. It is not visible externally. Eliminate this option.
Step 5: Recognize that the auricle (pinna) is the external, visible, funnel-shaped part of the ear that collects sound waves and directs them into the ear canal. This matches the description in the question.
