 Nervus cochlearis (acusticus): nervio nacido de las fibras eferentes del ganglio de Corti que atraviesan la lámina cribosa espiroidea de la base de la columela formando el nervio, una vez en el CAI, el nervio ocupa una situación antero-interna, es voluminoso y sus fibras se enrollan un poco sobre si mismas. Al unirse al vestibular forma el estatoacústico.
<(F.): Nerf cochléaire: branche auditive du huitième nerf crânien, compte environ 30.000 fibres afférentes chez l’homme. Ces fibres, qui se rassemblent dans le modiolus, sont les axones des neurones dont les corps cellulaires forment le ganglion de Corti. Le nerf cochléaire est, pour l’essentiel, le nerf des cellules ciliées internes. <(In.): Cochlear nerve: one of the two major branches of the eighth cranial nerve; a special sensory nerve for the sense of hearing that transmits impulses from the organ of Corti to the brain. This nerve originates from the Organ of Corti in the inner ear. Its delicate acoustic receptors lie in the hair cells of the organ connected to the peripheral fibers. The cell bodies of these bipolar neurons lie in the base of the boy spiral lamina. They are collectively called spiral ganglion. The central processes issue from the cell bodies and run in the cochlear nerve accompanied by the vestibular nerve, to reach the upper medulla at the floor of the fourth ventricle, which bulges to form the tuberculum acousticum. The fibers relay in two nuclei of the cochlear pathway. Root: Cochlear nuclear complex buried in the floor of the fourth ventricle at the tuberculum acousticum. Origen: Vestibulocochlear nerve; dorsal cochlear nucleus and Ventral cochlear nucleus. ANATOMIA: FUENTES DE INFORMACION BIOMEDICA: TERMINOS RELACIONADOS:
