Which of the following are two functions of the inner ear?

The inner ear is responsible for critical functions related to hearing and balance, making the correct answer regarding its functions the one that identifies these roles. Specifically, the inner ear contains the cochlea, which is essential for converting sound vibrations into neural signals that can be interpreted by the brain. This transmission of vibrations is integral to the process of hearing.

Additionally, the inner ear houses the vestibular system, which includes structures like the semicircular canals that contribute significantly to balance and spatial orientation. These canals detect rotational movements of the head, while other parts of the vestibular system help sense linear acceleration and gravitational forces, allowing the body to maintain equilibrium.

Thus, identifying transmits vibrations and maintains balance accurately reflects these two primary functions of the inner ear, highlighting its dual role in both auditory and vestibular processing.
