Question 10

Answer 10

Marginal branch of the cingulate gyrus

Question 11

Answer 11

Left side of image: crus of fornix, lateral ventricle, superior colliculus, cerebral aqueduct, basilar pons

Rightside of image: caudate, thalamus, medial geniculate body, lateral geniculate body, tail of caudate, inferior horn of lateral ventricle, hippocampus

Question 12

Answer 12

Paracentral lobule

Question 13

Answer 13

Postcentral gyrus

• not the superior frontal sulcus running vertically back from anterior and hitting the precentral sulcus, then central sulcus right behind the precentral sulcus
• also note the symmetric and large marginal branch of the cingulate gyrus which is just posterior to the central gyrus

Question 14

Answer 14

Anterior cerebral arteries

• this far anterior the arteries (despite being inferior) are the anterior (not the posterior) cerebral arteries
• PCA would be much more dorsal

Question 15

Answer 15

Optic radiations
