• symptoms
  • By administering betahistine to the damaged nerve over a long period of time, the process of vestibular compensation can be accelerated to alleviate symptoms. (wikipedia.org)
  • In some people, symptoms may include conjunctivitis, keratitis, uveitis, and optic nerve palsies that can sometimes cause chronic ocular inflammation, loss of vision, and debilitating pain. (wikipedia.org)
  • Anatomy
  • Because Latin was the lingua franca (common language) of the study of Anatomy when the nerves were first documented, recorded, and discussed, many nerves maintain Latin or Greek names, including the trochlear nerve (IV), named according to its structure, as it supplies a muscle that attaches to a pulley (Greek: trochlea). (wikipedia.org)
  • neurons
  • Second, it is derived from the Schwann cells of the associated nerve, rather than the actual neurons (neuromas). (wikipedia.org)
  • The cell bodies of many of the neurons of most of the cranial nerves are contained in one or more nuclei in the brainstem. (wikipedia.org)
  • Some of the cranial nerves have sensory or parasympathetic ganglia (collections of cell bodies) of neurons, which are located outside the brain (but can be inside or outside the skull). (wikipedia.org)
  • optic
  • The terminal nerves, olfactory nerves (I) and optic nerves (II) emerge from the cerebrum or forebrain, and the remaining ten pairs arise from the brainstem, which is the lower part of the brain. (wikipedia.org)
  • The cranial nerves are considered components of the peripheral nervous system (PNS), although on a structural level the olfactory, optic and terminal nerves are more accurately considered part of the central nervous system (CNS). (wikipedia.org)
  • cerebellopontine angle
  • The vestibulocochlear nerve is accompanied by the labyrinthine artery, which usually branches off from the anterior inferior cerebellar artery (AICA) at the cerebellopontine angle, and then goes with the 8th nerve through the internal acoustic meatus to the internal ear. (wikipedia.org)
  • The cerebellopontine angle is the site of the cerebellopontine angle cistern one of the subarachnoid cisterns that contains cerebrospinal fluid, arachnoid tissue, cranial nerves, and associated vessels. (wikipedia.org)
  • Damage
  • A decay of more than 25 decibels is indicative of damage to the vestibulocochlear nerve. (wikipedia.org)
  • TD is a powerful diagnostic procedure for RetroCochlearPathology (damage to the auditory nerve). (wikipedia.org)
  • The first symptom in 90% of those with an acoustic neuroma is unexplained unilateral sensorineural hearing loss, meaning there is damage to the inner ear (cochlea) or nerve pathways from the inner ear to the brain. (wikipedia.org)
  • However, it is much more common for treatment, rather than the tumor itself, to damage this nerve, leading to weakness or paralysis of the face. (wikipedia.org)
  • These nuclei are important relative to cranial nerve dysfunction because damage to these nuclei such as from a stroke or trauma can mimic damage to one or more branches of a cranial nerve. (wikipedia.org)
  • cervical
  • The great auricular nerve, auricular nerve, auriculotemporal nerve, and lesser and greater occipital nerves of the cervical plexus all supply sensation to parts of the outer ear and the surrounding skin. (wikipedia.org)
  • accurately
  • The actual value of any tone decay procedure in accurately identifying 8 cranial nerve pathology has not been extensively investigated[citation needed] Dhingra, L. and Dhingra, Shruti (2014). (wikipedia.org)
  • terminal
  • The neurotransmitters diffuse across the narrow space between the hair cell and a nerve terminal, where they then bind to receptors and thus trigger action potentials in the nerve. (wikipedia.org)
