Which of the following is not a function of the vestibular apparatus?

The cochlea is responsible for converting sound waves into nerve impulses that can be interpreted by the brain. The vestibular apparatus helps to maintain balance and spatial orientation. The vestibular apparatus is made up of the utricle, the saccule, and the semicircular ducts. The maculae of the utricle and saccule detect linear acceleration or deceleration and head tilt. The cristae in the ampullae of the semicircular ducts detect rotational acceleration or deceleration.
