2-Minute Neuroscience: Vestibulocochlear Nerve (Cranial Nerve VIII)

Welcome to Neuroscience 2 Minutes, I will explain neuroscience topics in 2 minutes or Less In this installment, I will explain the vestibular nerve The vestibulocochlear nerve consists of a vestibular and cochlear component They have the functions of transmitting information to the brain from the vestibular system and the cochlea Straight The information from the cochlea deals with the hearing, while the information from the vestibular system It deals with vestibular sensations, which include information about the position of the head And his movement This vestibular information enables us to maintain our balance and the stability of our head and body During movement and maintaining position The cochlear component begins in the eighth cranial nerve with neurons that make connections With hair cells, which are the sensory receptor cells of the auditory system When hair cells are activated, they transmit auditory signals to the cochlear portion From the nerve through changes in the levels of neurotransmitter release The cochlear nerve travels from the cochlea to the dorsal and ventricular nuclei of the cochlea Which is located at the junction between the qantara and the bone marrow From there, the auditory information is sent to areas in the brain stem and cortex Those involved in auditory processing The vestibular component of the nerve also receives stimulation from the hair cells But these cells are found in the vestibular system From there, the nerve travels to the vestibular cores of the arch and the bone marrow The vestibular nucleus consists of four nuclei: the inferior, middle and lateral vestibular nuclei, and the superior vestibular nucleus The striatum of neurons leaves each of these nuclei in different regions of the brain and brainstem And the spinal cord to coordinate head, eye and body movements to maintain balance and balance Besides other related posts Damage to the vestibulocochlear nerve can cause impairment of hearing or vestibular function This leads to symptoms such as hearing loss, tinnitus, dizziness and loss of balance And nausea Translation by: Chuan Hamid
