Neuroanatomy — Flashcards

Flashcard 131: The intermediate filament Glial Fibrillary Acidic Protein (GFAP) is found in _____ cells (e.g., astrocytes, ependymal cells, Schwann cells).

Answer: neuroglial

Flashcard 132: ID Brainstem Level: - Presence of 4th ventricle - Ventral enlargement - Presence of CN V Answer: _____

Answer: Rostral pons

Extra: Netters: Other:

Flashcard 133: There are _____ pairs of spinal nerves in total

Answer: 31

Flashcard 134: The _____ transmits sensory information for pain and temperature.

Answer: spinothalamic tract

Extra: The spinothalamic tract decussates in the spinal cord at the anterior white commissure and carries pain and temperature sensation.

Flashcard 135: Which dopaminergic pathway connects the ventral tegmentum (midbrain) to the prefrontal cortex? _____

Answer: Mesocortical pathway

Flashcard 136: Which dopaminergic pathway connects the substantia nigra pars compacta to the neostriatum? _____

Answer: Nigrostriatal pathway

Extra: The nigrostriatal pathway is one of the four major dopaminergic pathways in the brain. It project from the substantia nigra pars compacta (SNpc) to the striatum (caudate and putamen). Degeneration of this pathway is the hallmark of Parkinson's disease.

Flashcard 137: The rootlets of CN _____ exit between the olive and medullary pyramid

Answer: XII

Flashcard 138: Meningitis is defined as inflammation of the _____

Answer: leptomeninges

Extra: Atlas:

Flashcard 139: If only one tract is present in the dorsal column (fasciculus gracilis), the spinal cord level is _____

Answer: below T6

Extra: The fasciculus gracilis is present at all spinal levels, whereas the fasciculus cuneatus is only present at T6 and above. Therefore, below the T6 level, only the fasciculus gracilis is present in the dorsal column.

Flashcard 140: One component of the blood-brain barrier is _____ from astrocytes

Answer: foot processes
