2. CN III, IV, & VI
3. CN V, VII, & VIII
4. CN IX, X, XI & XII
5. Summary and Practice Questions
,REVIEW OUTLINE
● CN I - Olfactory n.
Cranial ○ Olfactory bulb
● CN II - Optic n.
Nerves ○ Optic tract
○ Optic chiasm
● CN III - Oculomotor n.
● CN IV - Trochlear n.
● CN V - Trigeminal n.
● CN VI - Abducens n.
● CN VII - Facial n.
● CN VIII - Vestibulocochlear n.
● CN IX - Glossopharyngeal n.
● CN X - Vagus n.
● CN XI - Accessory n.
● CN XII - Hypoglossal n.
, Clinical Case Study
A 42 year patient presents complaining of
blurriness in his peripheral vision. After performing
blood work you notice that his GH and IGF-1 levels
are through the roof. You then order and MRI to
confirm your initial diagnosis.
, Learning Outcomes
By the end of this lesson, students should be able to:
1. Name and identify the 12 pairs of cranial nerves
2. List the individual functions of each cranial nerve
3. Diagnose cranial nerve damage based on symptoms
