While vestibular branch or VIII cranial nerve forelace branch focuses on balance, vestibular branch nerve has two elements. Conductive hearing loss is caused by sound waves to the Corti organ to the ear canal or the middle ear. In sensorineural hearing loss, the lesion is in the inner ear, the vestibular cochlear nerve, or the brain. Unilateral sensory hearing loss is usually caused by damage to the nucleus or the nerve itself due to extensive bilateral connection of the ear.

Acoustic schwannoma (neuroma) is a well-balanced auditory nerve, a benign tumor that progresses from the inner ear to the brain. These nerves intertwine to form the vestibular cochlear nerve (the eighth cranial nerve). Stress from the tumor to the nerve may lead to hearing loss and imbalance

The labyrinth of the inner ear includes nerve endings of the vestibular nerve - balance nerves - and auditory nerves, which are branches of the vestibular nerve cells, or the eighth cranial nerve. Vestibular nerve endings supply vestibular semicircular canal and otolith. The auditory nerve supplies the cochlea. Diseases lost in the inner ear can affect the vestibular nerve and the auditory nerve. (Lucent 6)

Hair cells themselves have no urge to transmit to the central nervous system (CNS); they stimulate the nerve fibers they are connected to. These nerve fibers form a cochlea branch of the eighth cranial (vestibular cochlear nerve) nerve. In the central nervous system, information is passed to both the brainstem that controls reflex activity and the auditory cortex where sound perception and interpretation are performed. By comparing the inputs of the two ears, the brain can interpret the time of the left and right sounds to determine the location of the sound source. This is called binaural hearing

The hindbrain consists of two subregions called frontal lobes and proencephalopathy. Several cranial nerves are located in this brain area. Trigeminal nerve, abduction, facial nerve and vestibular nerve are found in the brain. Glossopharyngeal, vagus nerve, accessory nerve and sublingual nerve are located in forebrain. The fourth ventricle also extends through this region of the brain. The hindbrain helps regulate autonomic nervous function, maintain balance and balance, adjust motion, and communicate sensory information.
