1
Q

List the somatic motor cranial nerve nuclei and their function

A
  • oculomotor (III)
  • trochlear (IV)
  • abducens (VI)
  • hypoglossal (XII)

Drive eye and tongue muscles

2
Q

List the special visceral motor cranial nerve nuclei and their function

A
  • trigeminal (V) = chew
  • facial (VII) = grimace
  • glossopharyngeal (IX) = swallow
  • vagus (X) = speak
  • accessory (XI) = shrug
3
Q

List the autonomic motor cranial nerve nuclei

A
  • oculomotor (III): Edinger-Westphal
  • facial (VII): superior salivatory
  • glossopharyngeal (IX): inferior salivatory
  • vagus (X): dorsal
4
Q

List the somatic sensory cranial nerve nuclei and their function

A
  • trigeminal spinal (V) = pain, temp, touch
  • trigeminal principal (V) = vibration, light touch
  • trigeminal mesencephalic (V) = proprioception, jaw jerk
5
Q

List the special somatic sensory cranial nerve nuclei

A
  • optic (II)

- vestibulocochlear (VIII)

6
Q

List the visceral sensory cranial nerve nuclei

A
  • facial (VII)
  • glossopharyngeal (IX)
  • vagus (X)
7
Q

Briefly describe the corticobulbar tracts

A
  • begin in lateral part of motor cortex
  • information passes through internal capsule to brainstem
  • goes to motor nuclei, decussating at the level of the nucleus
  • supplies musculature of the head and neck
8
Q

What are the signs of a lesion affecting cranial nerve function?

A
  • eye muscle weakness
  • loss of face sensation
  • problems speaking, swallowing
  • vertigo
  • changes in taste/hearing
