5. Auditory cortex is stimulated.
Sound is received by external ear or pinna that travels into the ear canal and causes the eardrum or tympanic membrane to move. The tympanic membrane vibrates with sound waves. Sound vibrations move through the ear bones or ossicles to the cochlea and cochlea moves due to sound vibration. Fluid movement causes the hair cells to move. As hair cells move up and down, electrical signals is generated. The auditory nerve sends electrical signal to the brain, which turns it into a sound.
