Question

Quizplus · Accepted Answer

The auditory nerve is responsible for relaying action potentials from the ear to the brain.

Answer: B
 The organ of Corti is located within the cochlea of the inner ear and is responsible for converting sound waves into electrical signals that can be transmitted to the brain via the auditory nerve.

Answer: D
 The elastic membrane within the cochlea creates pressure waves in the cochlear fluid, which is necessary for the detection and processing of sound.

Answer: H
 The vestibular nerve is responsible for detecting acceleration, maintaining balance and position, and aiding in spatial orientation.

Answer: I
 Frequency is measured in Hertz (Hz), which is the number of wave cycles per second. The perception of pitch is dependent on the frequency of the sound wave.
