Brainstem nuclei Flashcard Deck - 10 Cards
Flashcard 11: 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.
Flashcard 12: The _____ is the brainstem nucleus that receives **visceral sensory** information (e.g., taste, baroreceptors, chemoreceptors) from CN VII, IX, and X.
Answer: nucleus solitarius
Extra: The **nucleus solitarius** receives visceral sensory information from cranial nerves VII, IX, and X.
**Mnemonic:** **S**olitarius = **S**ensory (taste, baroreceptors, chemoreceptors).
Contrast with:
* **Nucleus Ambiguus:** Motor (efferent) to pharynx, larynx, and upper esophagus.
* **Dorsal Motor Nucleus:** Parasympathetic (autonomic) fibers to the heart, lungs, and GI tract.
Flashcard 13: The cranial nerve nucleus located in the **caudal midbrain** (at the level of the inferior colliculus) that innervates the contralateral superior oblique muscle is the _____.
Answer: Trochlear nucleus
Extra: The trochlear nerve (CN IV) is the only cranial nerve that decussates and exits the brainstem from the dorsal aspect. It innervates the superior oblique muscle.
Flashcard 14: The _____ nucleus is the portion of the medial longitudinal fasciculus responsible for vertical gaze
Answer: rostral interstitial
