Chapter 1: Brain anatomy Flashcards
voor en na de central sulcus zitten de…
precentral and postcentral gyrus
welke lobes divide de central sulcus
frontal and parietal
grey matter of the cortex consists of … layers
6 laminae
layer 1 grey matter cortex
no cell bodies, mostly axons and dendrites
layer 2-3
pyramidal cells, connected to local cortical sites
layer 4
stellate cells, connected to thalamus
layer 5-6
large pyramidal cells, output leaves the cortex via these cells
hoe zijn deze layers georganiseerd
in banden van 0.5 mm wijd: cortical colums
Brodmanns areas
the brain can be divided into 50 cytoachitectonic areas, based on cellular composition
function of ventricles
protect the brain, clean during sleep. filled with CSF
what are the two main sources of blood for the brain
vertebral arteries and internal carotid arteries
vanaf lateral view, welke van vertrebral en internal carotid zit voor en welke zit achter
internal carotid zit voor, vertebral zit achter (bij wervelkolom)
waar lopen de vertebral arteries in elkaar
merge into de basilar artery, op het level van de pons.
waar meeten de internal carotid artery en basilar artery
in de circle of willis
dus welke twee zorgen samen voor circle of willis
internal carotid artery and basil artery
all neurons have the same structure:
dendrites, soma, axon, axon terminals
resting membrane potential
-70 mv
