The cochlear nerve conducts impulses from the receptors located within the cochlea. The inner ear consists of the cochlea and several non-auditory structures. It is found within the scala tympani and scala vestibuli of the cochlea. These connect to the semicircular canals and the cochlea. The inner hair cells provide the main neural output of the cochlea. Sinuses may reflect vibrations towards the cochlea. Damage to the inner ear (cochlea) may be caused by temporal bone fracture. Sound is analyzed in term of pressure waves sensed by the cochlea in the ear. Sensorineural hearing loss is caused by a problem in the inner ear, the cochlea. This is an electronic device that replaces the cochlea of the inner ear. Hearing impairment may be associated with damage to the hair cells in the cochlea. IGF-1 shapes the development of the cochlea through controlling apoptosis. The placement of vibration on the cochlea depends upon the frequency of the presented stimuli. These nuclei also form the source of the olivocochlear bundle, which innervates the cochlea. However, the stimulation can happen also via direct vibration of the cochlea from the skull.
