Question: 1 / 2700

The outer ear consists of which two main components?

Cochlea and auditory canal

Auricle and auditory canal

The outer ear is primarily made up of the auricle, also known as the pinna, and the auditory canal. The auricle is the visible outer part of the ear that collects sound waves and directs them into the auditory canal. The auditory canal is the passage that leads from the outer ear to the eardrum, facilitating the movement of sound waves to the inner structures of the ear.

The cochlea, found in the inner ear, is responsible for converting sound vibrations into neural signals, while the eardrum acts as a barrier between the outer ear and the middle ear but is not classified as part of the outer ear itself. This distinction is crucial for understanding the anatomy of the ear and how sound is processed. Thus, the combination of the auricle and the auditory canal accurately represents the two main components of the outer ear.
