In which part of the brainstem is the hypoglossal nucleus located?

Explanation:
The hypoglossal nucleus is located in the medulla oblongata, specifically in the rostral (upper) part near the floor of the fourth ventricle. Its neurons form the motor nucleus for the tongue, and their axons exit between the pyramid and the olive as the hypoglossal nerve. That places it firmly in the upper medulla, not in the pons or midbrain, and not in the caudal (lower) medulla.
