Where is the oculomotor nucleus located?

Explanation:
The nucleus of the oculomotor nerve is in the midbrain, specifically the rostral (upper) midbrain, in the tegmentum around the cerebral aqueduct. From this nucleus, the oculomotor fibers travel forward and exit the brainstem at the interpeduncular fossa to form the oculomotor nerve. This placement in the upper midbrain explains why the nucleus isn’t located in the pons or medulla and why it lies above those regions.
