|
longitudinal fissure
|
midline saggital suture, separates brain into hemispheres
|
|
|
5 lobes of cerebral hemishpere
|
frontal, parietal, occipital, temporal, insula
*limbic system sometimes given own lobe (limbic lobe) |
|
|
lateral fissure
|
also called Sylvian fissure, separates parietal and temporal lobes
|
|
|
central sulcus
|
also called Rolandic sulcus, separates frontal and parietal lobes
*to find it look for 2 parallel gyri, not always obvious |
|
|
parieto-occipital sulcus
|
on medial surface of hemisected brain, separates occipital lobe from the rest of the brain
|
|
|
insula
|
buried in lateral fissure, find by removing other lobes
|
|
|
pre-central gyrus
|
somato-motor cortex, controls volitional movements of contralateral side of the body
|
|
|
frontal gyri
|
superior, middle, and inferior
inferior separated into opercular, triangular, and orbital |
|
|
Broca's Area
|
on dominant hemisphere, opercular and triangular parts, produce speech and use language

divided by intraparietal sulcus into superior and inferior lobules
|
|
|
inferior parietal lobule
|
2 adjacent gyri, supramarginal (caps lateral fissure) and angular (caps superior temporal sulcus)
|
|
|

limbic system
|
cingulate gyrus, parahippocampal gyrus, subcallosal gyrus, and hippocampus (including uncus)
|
|
|
insula functions
|
gustatory and visceral sensation
