falx cerebri

layer of dura matter

what are subarachnoid cisterns ?

widened areas of the subarachnoid space that are filled with CSF

where is CSF produced and reabsorbed?

• produced: in ventricles

• reabsorbed: dural sinus

add multiple choice

what are the ventricles filled with?

CSF

remind horns

septum pellucidum

thin walls that separates ventricles

nucleuses

• caudate nucleus

• lentiform nucleas

order from inside out of middle brain

• corpus callosum

• lateral ventricle

• caudate nucleus

• internal capsule

• lentiform nucleus

• external capsule

• colostrum

3 major basal ganglia

• lentiform

• caudate nucleus

• colostrum

Insula

• in temporal lobe

• considered 5th lobe

lateral fissure

• middle cerebral artery runs through here

third ventricle

always between thalamus

superior sagittal sinus

• venous return

• venous return is towards the back

• arterial flow is in the middle
