Gross Anatomy of the Brain - Lecture 5 Flashcards
gross divisions of the brain
cerebrum
diencephalon
cerebellum (cerebral cortex, white matter, basal ganglia)
brainstem
Brodmann’s classification
a system for the fxnal regionalization of the cerebral cortex
what does teh brodmann’s classification do
mapped the cortex into 47 unique areas
each with specific characteristics
map was expanded to more than 200 areas today
some areas associated to nervous fxn
areas 41 and 42
areas 1-3
areas 17 and 18
areas 41 and 42
temporal lobe
related to hearing
areas 1-3
in the postcentral gyrus of the parietal lobe
the somatosensory region
areas 17-18
in the occipital lobe
primary visual areas
cerebral cortex
frontal lobe
parietal lobe
temporal lobe
occipital lobe
insula
limbic lobe
frontal lobe
extends from the frontal pole to the central sulcus
parietal lobe
extends from the central sulcus to the pareito-occipital sulcus
temporal lobe
inferiorly to the lateral fissure and anterior to the parieto-occipital sulcus
“thumb of the boxing glove”
occipital lobe
extends from the pareito-occipital sulcus to the occipital pole
insula
forms the floor of the lateral sulcus
what is the insula involved in
diverse fxns
usually linked to emotion or the regulation of the body’s homeostasis
fxns of the insula
perception
motor control
self-awareness
cognitive fxning
interpersonal experience
