Where is the nucleus ambiguus located?

Explanation:
Nucleus ambiguus is a motor nucleus for the vagus and glossopharyngeal nerves, supplying muscles of the pharynx, larynx, and soft palate. It sits in the brainstem’s medulla, specifically in the rostral to middle (upper and mid) portion, in the ventrolateral area. This placement in the upper to mid medulla explains why the correct location is in the medulla’s rostral/mid region rather than in the pons, midbrain, or lower medulla.
