Reticular formation — Flashcards

Flashcard 1: Which brainstem nucleus is located adjacent and lateral to the hypoglossal nucleus in the medulla?

Answer: Dorsal motor nucleus of CN X (Vagus nerve)

Flashcard 2: Which brainstem nuclei are responsible for mediating the pupillary light reflex?

Answer: Pretectal nuclei

Extra: The pretectal nuclei receive bilateral input from the optic tracts and project to the Edinger-Westphal nuclei (parasympathetic part of CN III), mediating the direct and consensual pupillary light reflexes.

Flashcard 4: Which brainstem nucleus is located near the midline in the floor of the fourth ventricle, just lateral to the medial longitudinal fasciculus (MLF)?

Answer: Abducens nucleus (CN VI)

Flashcard 6: The _____ is the brainstem nucleus that receives pain and temperature sensation from the face.

Answer: spinal trigeminal nucleus

Extra: The spinal trigeminal nucleus extends from the pons through the medulla to the upper cervical spinal cord. It receives pain and temperature afferents from CN V, VII, IX, and X.
