Explain The Sound-Induced Contractions Of The External Ear

The pinna’s main purpose is to direct the sound waves from the outer ear into the auditory canal and help detect where abouts the sound is coming from. The Stapes (Stirrups) located in the inner ear resting against the oval window. This connects to the middle bone called the incus and the incus connects with the Malleus. Sound-induced vibrations of the tympanic membrane are amplified and transmitted through these ossicles to the inner ear. The Cochlea contains the organ of Corti which is a structure that is made up of thousands of specialised sensory hair cells. Vibrations transmitted from the middle ear are transmitted as waves in the fluid. The hair cells convert the vibrations from the middle of the ear into signals that are sent via the
