Neuroanatomy Week 2
1. the midbrain is the: relay system
2. which part of the brainstem contains Reticular formation, cranial nerve nuclei,
spinal tracts, substantia nigra, and red nucleus: midbrain
3. what cranial nerves are located in the midbrain: CN III and CN IV
4. the midbrain is significant in what type of palsies: oculomotor nerve palsies
5. the pons is the origin of which cranial nerves: CN 5-8
6. which part of the brainstem is the most inferior portion and connects to the
spinal cord: medulla oblongata
7. which regulation system is located in the medulla oblongata: cardiovascular respira-
tory regulation system
1/5
, 8. which cranial nerves originate in the medulla oblongata: CN 9-12
9. where do motor neurons cross: medulla oblongata (pyramidal decussation)
10. midbrain function: •Most eye movements
• Processing vision and hearing
• Substantia nigra: Dopamine
11. pons function: sleep-wake cycle
12. medulla oblongata function: •Cardiovascular and respiratory system links together
• Manages: Coughing, sneezing, swallowing, vomiting, and maintaining balance
13. what is the name of the area that contains primary visceromotor and vis-
cerosensory nuclei and serves as a landmark for neurosurgical procedures
located in the medulla oblongata: vagal trigone
14. reticular formation is part of the brainstem that is a complex network of: -
brainstem nuclei and neurons
