Definition
  1. Noun:
    • The nerve that carries auditory information from the inner ear to the brain: The auditory nerve is the bundle of nerve fibers responsible for transmitting sound signals. It connects the cochlea of the inner ear to the brainstem.
Usage Examples
  • Noun:
    • Damage to the auditory nerve can result in permanent hearing loss.
    • The signal travels from the cochlea via the auditory nerve to the brain for processing.
    • Surgeons must be extremely careful not to injure the auditory nerve during the operation.
Advanced Usage
  • Clinical context: Often discussed in medical and audiology fields concerning hearing disorders, diagnostics (like auditory brainstem response tests), and treatments such as cochlear implants, which directly stimulate this nerve.
    • The cochlear implant bypasses damaged hair cells to directly stimulate the auditory nerve.
Variants and Related Words
  • Vestibulocochlear nerve (Cranial Nerve VIII): The full anatomical name for the nerve bundle that includes both the auditory (cochlear) and vestibular (balance) components.
    • The vestibulocochlear nerve is the eighth cranial nerve.
  • Cochlear nerve: A term sometimes used synonymously with the auditory nerve, though it technically refers specifically to the part concerned with hearing.
    • The cochlear nerve is the auditory branch of the vestibulocochlear nerve.

  • Acoustic nerve: An older, but still occasionally used, term for the auditory nerve.
    • The tumor was found to be pressing on the acoustic nerve.
Related Phrases and Terms
  • Nerve deafness (Sensorineural hearing loss): A type of hearing loss often caused by damage to the auditory nerve or the inner ear's hair cells.
    • His condition was diagnosed as nerve deafness due to auditory nerve damage.
  • Auditory pathway: The neural route from the ear to the auditory cortex in the brain, of which the auditory nerve is the first crucial link.
    • The auditory pathway begins with the auditory nerve.
