Neuroanatomy 4

Question 1

what do we find in the retrolenticular region

Answer 1

this is the region caudal to the lentiform nucleus and it carriers the optic radiation from the lateral geniculate nucleus of the thalamus to the visual cortex

Question 2

what do we have in the sublenticular region

Answer 2

this is where we have fibres run from the medial geniculate nucleus to the primary auditory cortex - which is on the transverse temporal gyri if you remember

Question 3

whats the blood supply to the internal capsule anterior limb

Answer 3

MCA and ACA

Question 4

whats the blood supply to the genu of the internal capsule

Answer 4

ACA, MCA and ICA

Question 5

whats the blood supply to the posterior limb of the internal capsule

Answer 5

ICA - anterior choroidal artery and the MCA

Question 6

whats the blood supply to the retrolenticular region and the sublenticular region

Answer 6

ICA - anterior choroidal artery and the PCA

Question 7

what are our association fibres in the brain

Answer 7

superior longitudinal fasciculus, uncinate fasciculus and the arcutate fasciculus

Question 8

what is the corona radiata

Answer 8

The corona radiata is a large white matter sheet in the brain, essentially a fan-shaped collection of ascending and descending axonal bundles, that connects the cerebral cortex with the thalamus, brainstem, and spinal cord.

Question 9

where does the corona radiata travel through

Answer 9

through the thalamus
