Test: Psychology and Sociology - 3 - MCAT MCQ

The cochlea is responsible for converting sound waves into electrical signals and transmitting them to the auditory nerve.

Hair cells in the cochlea are responsible for converting sound waves into electrical signals that can be interpreted by the brain.

The vestibular system, which includes the semicircular canals and otolith organs, helps maintain equilibrium and balance.

The primary auditory cortex, where sound information is processed, is located in the temporal lobe of the brain.

The inner ear, specifically the cochlea, detects the frequency of sound waves.

The amplitude of sound waves determines the perception of loudness. Higher amplitudes correspond to louder sounds.

The smallest bone in the human body, the stapes, is located in the middle ear and plays a crucial role in transmitting sound vibrations to the inner ear.

Sensorineural hearing loss is typically caused by damage to the hair cells in the cochlea or the auditory nerve.

Auditory integration is the process by which the brain combines different sound wave frequencies into a coherent sound.

The ossicles (malleus, incus, and stapes) amplify sound waves in the middle ear before they are transmitted to the inner ear.

The vestibular system detects changes in head position and movement, contributing to our sense of balance.

Sound localization refers to the ability to locate the source of a sound in space. It relies on the brain's interpretation of differences in sound arrival times and intensities between the ears.

Conductive hearing loss is typically caused by a blockage or damage to the outer or middle ear, which hinders the transmission of sound waves to the inner ear.

The ossicles (malleus, incus, and stapes) mechanically amplify sound waves in the middle ear before they reach the cochlea.

The perception of pitch is determined by the frequency of sound waves. Higher frequencies are perceived as higher pitches, while lower frequencies are perceived as lower pitches.
