Neuroanatomy — Flashcards

Flashcard 351: One component of the blood-brain barrier is _____ between non-fenestrated capillary endothelial cells

Answer: tight junctions

Flashcard 352: What is the destination of the ventral anterior (VA) / ventral lateral (VL) nuclei of the thalamus? _____

Answer: Premotor and primary motor cortex

Flashcard 353: Which brainstem tract coordinates conjugate horizontal eye movements by connecting the nuclei of CN III, IV, and VI?

Answer: Medial longitudinal fasciculus (MLF)

Extra: The MLF coordinates conjugate horizontal eye movements by connecting the abducens nucleus (CN VI) in the pons to the contralateral oculomotor nucleus (CN III) in the midbrain. A lesion in this tract results in internuclear ophthalmoplegia (INO), often seen in multiple sclerosis.

Flashcard 354: Alpha-MSH and beta-MSH are produced in the _____ lobe of the pituitary gland, which is rudimentary in adult humans

Answer: intermediate

Flashcard 355: Identify the brainstem level characterized by the following features: - Presence of the 4th ventricle - Ventral enlargement (basilar pons) - Presence of CN VI and VII nuclei/fibers

Answer: Caudal pons

Flashcard 356: Conduction aphasia is caused by damage to the _____, which is a large fiber bundle that connects Broca's area with Wernicke's area

Answer: arcuate fasciculus

Flashcard 357: Which branch of the basilar artery supplies the anterior inferior surface of the cerebellum?

Answer: Anterior inferior cerebellar artery (AICA)

Flashcard 358: One component of the basal ganglia is the _____, which is located in the diencephalon

Answer: subthalamic nucleus

Flashcard 359: The nucleus _____ receives visceral sensory information (e.g. taste, baroreceptors, gut distention)

Answer: solitarius

Flashcard 360: Which ascending spinal tract is responsible for transmitting pain and temperature sensations?

Answer: Spinothalamic tract
