consistency like cold porridge: shearing between parts/meninges
no room for expansion (meningitis - � down underneath skull, compress brainstem, judge clinically braindead)
CSF continually production � ventricles
contained between pia arachnoid + arachnoid layer
arachnoid gradients
� sitting between two hemispheres down the central sulcus
sagittal sinus here
occiput � back/bottom
central sulcus � divides front/parietal lobe
pre-central � motor
superior � up, inferior � down
anterior/ventral � front
posterior/dorsal � back
rostral/cranial � head (going higher)
caudal � going lower
superficial � near surface
deep � further inside
sagittal � plane chopping from front � back
suture on the skull bone
mid-sagittal � centre-parting
para-sagittal � moving parallel
coronal plane � side to side
suture � ear � ear
horiz/axial � plane eyes deeper
lateral/medial relative
to the mid-sagittal plane
orbito � eyes
ventricles produce CSF � 4 � drain out of the 4th through the aqueduct of Sylvium � midline canal of spinal cord
superior colliculus � co-ordination of eye movements
inferior colliculus � auditory pathway
optic chiasm � nasal fibre crosses
masa intermedia - � connecting the thalami
pituitary tumour � lose temporal vision
fornix (in the limbic system) � inferior to the corpus collosum
topographical representation of homunculus � cranial � lateral
for somatosensory + motor
anosnic(???) � no sense of smell
deccisatoin � spreading/flowing out
homonomous hermiaopia(???)
