sensory: smell
olfactory I
sensory: vision

oculomotor III
motor: movement of the eyeball
trochlear IV
sensory: cutaneous sensations from ophthalmic

glossopharyngeal IX
sensory: general senses from the pharynx and epiglottis
motor: swallowing, coughing, speech
vagus X

accessory XI
motor: swallowing and speech
hypoglossal XII
brain and spinal cord are covered and protected by three connective tissue membranes called
meninges
outermost meninx
leathery
double layered membrane
dura mater
two layers of the dura mater
periosteal layer and meningeal layer
attached to the inner surface of the skull nad forms the periosteum
periosteal layer
forms the outermost brain covering and is continuous with the dura mater of the spinal cord
meningeal layer
in longitudinal fissure only
extension
attaches the crista galli of ethmoid bone if the skull
falx cerebri
cavity created by falx cerebri which collects blood draining from the brain tissue
superior sagittal sinus
inward fold in the inner dural membrane
separates the two cerebellar hemispheres
falx cerebelli
inward fold in the inner dural membrane
separating the cerebrum from the cerebellum
tentorium cerebelli
middle meninx
weblike
underlies the dura mater and is partially separated from it
arachnoid mater
separates the arachnoid mater and dura mater
subdural space
innermost meninx
delicate and highly vascular and clings to the surface of the brain
pia mater
