Flashcard 8: Identify the cranial nerve nucleus based on the following anatomical features: - Located in the **rostral midbrain** - **Anterolateral** to the cerebral aqueduct - **Anterior** to the Edinger-Westphal nucleus

Answer: Oculomotor nucleus (CN III)

Extra: The oculomotor nucleus is located at the level of the superior colliculus (rostral midbrain). The Edinger-Westphal nucleus (parasympathetic) lies dorsal (posterior) to the somatic motor nucleus.

Flashcard 9: paramedian pontine reticular formation (PPRF)

Answer: eyes look away from side of lesion

Flashcard 10: Where is the locus ceruleus located?

Answer: pons
