lateral surface of the brain Flashcards
pia mater
arachnoid mater
dura mater
dural venous sinuses
middle artery
extradural space purpose
a potential space containing meningeal vessels
subdural space purpose
contains veins connecting cerebral veins to dural venous sinuses
subarachnoid space purpose
contains cerebral vessels and csf
subpial space
non-existent since the pia adheres to the cortical surface
cistern definition
any of the openings in the subarachnoid space of the brain filled with cerebrospinal fluid

longitudinal fissure purpose
seperates the two hemispheres in the midline
lateral fissure purpose
- consists of a stem and 3 rami (anterior horizontal, anterior ascending, and posterior)
- asymmetry between right and left sides
- seperate the margins of the lateral sulcus anteriorly to see the insula and the middle cerebral vessels
