temporal
occipital
(parietal)
ventral side of the brain stem and cerebellum sits where
in posterior fossa
temporal lobes sit in which fossa
middle cranial

anterior cranial
what are the ridges of the brain called
gyri
what are the valleys of the brain called
sucli
what does the central sulcus seperate
frontal lobe (rostrally)
parietal lobe (caudally)
true or false: central sulcus separate the parietal and occipital lobes
false, the frontal and parietal
what does the lateral issue seperate
separates between the temporal lobe mentally and the frontal and parital lobes dorsally
which fissure delimits the two cerebral hemisphere
median longitudinal fissue
which fissure delimits the temporal bone
lateral fissure
which sulcus delimits the parietal and occipital lobes
parietooccipital sulcus
which sulcus lies between frontal and parietal lobes
central sulcus
true or false: the central fissure is not continuous with the lateral fissure
true
where is best to identify the parietooccipital sulcus
medially
what orientation are the pre central and post central gyri
dorsoventral
