Internal Cranium / 2 Flashcards
two types of intracranial hemorrhages
venous, arterial
blank leptomeningitis is often deadly
bacterial
more dangerous hemorrhage in brain
artery
dural folds function
separate hemispheres and compartments of brain
internal jugular begins at the end of blank sinus
sigmoid
diencephalon has the blank
thalami
thalamus acts as a blank center
sensory relay
too much fluid in csf spaces of brain and ventricles
hydrocephalus
hydrocephalus can be dangerous because it does this to brain
compresses
internal carotid arteries of circle of willis supplies blank part of brain
anterior
middle cerebral artery supplies blank and blank part of brain
external/lateral
3,7,9,10 is blank/blank
parasympathetic/efferent
cn 1
olfactory
olfactor nerve exits cranium through blank of blank
foramina, crib plate ethmoid
olfactory nerve has a blank and blank
bulb, tract
cn 2
optic nerve
olfactory functional area and end of pathway (part of brain interpreting smell)
Uncus of temporal lobe
optic nerve exits/enters cranium at blank
optic canal
optic nerve goes to the blank like most nerves
thalamus
thalamus is for blank information
sensory
left blank sees blank visual fields
cortex, right
longer the pathway, the easier it is for a blank
disturbance (pathology)
oculomotor nuclei are in the blank and thats where it leaves
midbrain
targets of oculomotor
recti/oblique muscles of eye (besides exceptions) (voluntary)
ciliary ganglion is where blank
parasympathetic pre/pos synaptic start/end
ciliary muscles (oculomotor) cause blank of pupil
constrict
zonular fibers are blank
suspensory ligaments
relationship between muscle and suspensory ligaments is blank
inverse
constricted pupils from ciliary muscles contraction allows blank of suspensory ligaments which creates blank lens
relaxing, thick
cranial nerve 4
trochlear
trochlear nerve exits cranium at blank
superior orbital fissure
trochlear nerve innervates blank
superior oblique muscle
