Which of the following is the correct sequence of structures involved in hearing a sound?
Pinna-Auditory canal-Tympanic membrane -Malleus-Incus-Stapes-Cochlea-Auditory nerve
Pinna is the external projection of the ear that receives signals in the form of sound vibrations which then passes through the auditory canal to reach the eardrum or tympanum. The pinna, auditory canal, and the eardrum make up the outer ear. Malleus, incus, and stapes are the three tiny bones of the mid-ear while cochlea is a part of the inner ear. The auditory nerve sends the signals to the brain.
