context_page_description: A cranial nerve nucleus is a collection of neurons in the brain stem that is associated with one or more cranial nerves. Axons carrying information to and from the cranial nerves form a synapse first at these nuclei. Lesions occurring at these nuclei can lead to effects resembling those seen by the severing of nerve they are associated with. All the nuclei except that of the trochlear nerve supply nerves of the same side of the body.
context_section_description: This list documents nuclei by the part of the brain they are found in:
  Nuclei present in the Midbrain
  Mesencephalic trigeminal nucleus (V) - sensory
  Red nucleus - motor, extrapyramidal
  Trochlear nucleus (IV) - motor
  Oculomotor nucleus (III) - motor
  Accessory nucleus or Yakubovich's nucleus (III) - visceromotor
  Nuclei present in the Pons
  Cochlear nuclei (VIII) - sensory
  Dorsal cochlear nucleus
  Ventral cochlear nucleus
  Vestibular nuclei (VIII) - sensory
  Salivary nuclei - visceromotor
  Inferior salivary nucleus (IX)
  Superior salivary nucleus (VII)
  Facial nucleus (VII) - motor
  Abducens nucleus (VI) - motor
  Trigeminal motor nucleus (V) - motor
  Main trigeminal nucleus (V) - sensory (fine touch and vibration)
  Nuclei present in the medulla
  Hypoglossal nucleus (XII) - motor
  Dorsal motor nucleus of vagus nerve (X) - visceromotor
  Nucleus ambiguus (IX, X, XI) - motor
  Solitary nucleus (VII, IX, X) - sensory
  Spinal trigeminal nucleus (V) - sensory (crude touch, temperature and pain)
  Inferior olivary nucleus afferent fibres to cerebellum
