Neuroanatomy — Flashcards

Flashcard 421: Which nucleus receives pain and temperature sensation from the face and extends from the pons into the upper cervical spinal cord?

Answer: Spinal trigeminal nucleus

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

Flashcard 422: The motor/sensory areas corresponding to the face are located in the _____ aspects of the pre-/post-central gyri (medial or lateral)

Answer: lateral

Flashcard 423: Which cranial nerve provides sensory innervation to the face and motor innervation to the muscles of mastication?

Answer: CN V (Trigeminal nerve)

Flashcard 424: The 1st-order neurons of the spinothalamic tract are sensory nerve endings with cell bodies located in a _____

Answer: DRG

Flashcard 425: What gyrus is located immediately superior to the corpus callosum?

Answer: Cingulate gyrus

Flashcard 426: The dorsal spinocerebellar and cuneocerebellar tracts enter the cerebellum via the _____

Answer: inferior cerebellar peduncle

Flashcard 427: Which thalamic nucleus receives visual input from CN II? _____

Answer: Lateral geniculate body (LGB)

Flashcard 428: Which sulcus separates the frontal lobe from the parietal lobe?

Answer: Central sulcus (Sulcus of Rolando)

Extra: The central sulcus separates the **frontal lobe** (precentral gyrus/motor cortex) from the **parietal lobe** (postcentral gyrus/sensory cortex).

Flashcard 429: Which nucleus of the Hypothalamus is responsible for both thermoregulation and sexual behavior?_____

Answer: Preoptic Nucleus

Flashcard 430: What is the destination of the medial geniculate body (MGB) of the thalamus? _____

Answer: Primary auditory cortex (temporal lobe)
