Neuroanatomy — Flashcards

Flashcard 11: Which spinal nerves exit above their corresponding vertebrae?

Answer: C1-C7

Flashcard 12: Which spinal nerves exit below their corresponding vertebrae?

Answer: C8, T1-T12, L1-L5, S1-S5, Co1 (i.e. all but C1-C7)

Flashcard 13: anterior spinothalamic tract (STT)

Answer: crude touch, pressure

Extra: immediately upon entering spinal cord Number 7

Flashcard 14: Identify the structure labeled '4' in the spinal cord cross-section:

Answer: Posterior horn (Dorsal horn)

Flashcard 15: Identify the structure labeled as number 6 in the provided spinal cord cross-section image:

Answer: Grey matter (of the spinal cord) :: identified as #6 in the image

Flashcard 16: Identify the structure labeled as 'number 8' in the spinal cord cross-section image.

Answer: anterior horn

Flashcard 17: middle cerebral artery (MCA)

Answer: lateral motor cortex, lateral sensory cortex, Wernicke's area, Broca's area

Extra: arm/facial paralysis and sensory loss, aphasia/hemineglect

Flashcard 18: What structures are supplied by the lateral striate (lenticulostriate) arteries (branches of the MCA)?

Answer: Striatum (caudate and putamen) and the internal capsule (chiefly the posterior limb).

Extra: These are known as the 'arteries of cerebral hemorrhage'. Rupture commonly causes contralateral hemiparesis/hemiplegia due to involvement of the posterior limb of the internal capsule.

Flashcard 19: Identify the structure labeled 'number 1' in the provided image.

Answer: Fasciculus cuneatus :: Identified as 'number 1' in the diagram.

Flashcard 20: Identify structure #2 in the provided cross-section of the spinal cord: <div>(Image on back)</div>

Answer: Fasciculus gracilis::Identify the structure labeled '2' in the image.
