Lab 1 + 2 Flashcards
layer of dura mater that touches skull
endosteal
2 layers of dura mater
endosteal, meningeal
this mater actually folds with the gyri and sulci
pia
space filled with csf
subarachnoid space
pockets in the brain that are filled with csf
cisterns
maters come together when we get the blank nerve
peripheral
tiny inner dot of spinal cord
central canal
anterior roots carry blank impulses
motor
hemmorage of the meningeal artery
epidural hemorrhage (hematoma)
anterior system of brain vasculature is supplied by the blank
internal carotid artery
posterior system of brain is supplied by the blank
vertebral artery
nerves are in the blank but tracts are in the blank
pns, cns
hemorrhage of the veins/sinuses in the subarachnoid space
subdural hematoma
4 important veins of brain
superior sagittal sinus, superficial cerebral veins, transverse sinus, straight sinus
a cva is due to a blank or a blank
hemorrhage, blockage
cva due to a blockage is called a blank
ischemic stroke
an ischemic stroke shows up in a ct scan as blank instead of blank
dark, white
excitatory action potential causing substance in brain that is released when depolarization occurs
glutamate
how many ventricles
2 lateral, third, and fourth
all ventricles are blank
interconnected
tissue within ventricles that produces csf
choroid plexus
half life of csf
3 hours
infundibulum is aka the blank
pituitary stalk
blood in the ventricles is aka
intraventricular hemorrhage
build up of white blood cells in brain blood vessels
chronic atherosclerosis
little man, that represents a person
homunculus
blockage in the aca causes blank deficits
feet
blockage in mca impairs blank
arms, face, speech
blockage in the pca impairs blank
vision
CNS has blank and blank as PNS has ganglia and nerves
nuclei, tracts
this is responsible for motivated behavior in brain (four f’s)
hypothalamus
outside of the brain is blank matter
gray
inside of the spinal cord is blank matter
gray
dural sac ends at blank and is attached to coccyx via blank
s2, filum terminale
where csf is drawn from in punctures
lumbar cistern
bacterial and viral infections of the meninges lead to
meningitis
ventricle extending through every lobe of the cerebral cortex
lateral ventricle
how lateral ventrical connects to third ventricle which separates the blank
interventricular foramen, diencephalon
third ventricle becomes the blank as it narrows posteriorly
cerebral aqueduct
the cerebral aqueduct opens into the blank at the level of the pons/cerebellum
fourth ventricle
