the Cerebrum Flashcards
sulci
grooves or depressions
gyri
ridges or elevations
corpus callosum
connects two cerebeal hemispheres togather
central sulcus
grooves seperating the frontal and parietal lobes
lateral sulcus
groove seperating the frontal and parietal lobes from the temporal lobe
precentral gyrus
- ridge directly anterior to the central sulcus
2. location of primary motor cortex
post central gyrys
- ridge directly posterior to the central sulcus
2. location of primary somatosensory cortex
superior temporal gyrys
- ridge located inferior to the lateral sulcus
function of frontal lobe
- personality
- mood
- language
- social conduct
anterior cerebral arteries
supply the anterior medial part of the cerebrum
middle cerebral arteries
supply most of the lateral portions of the cerebrum
posterior cerebral arteries
- branches of the basilar arteries
2. supply medial and lateral sides of the cerebrum posteriorly
cerebrovascular haemorrhage / Stroke
“an abrupt loss of focal brain function lasting more than 24 hours due to either spontaneous haemorrhage into brain substance or inadequate blood supply to part of the brain i.e. ischaemia (thrombosis, embolism)“.
frontal lobe stroke
- personality and behavioral chanages
2. inability to solve problems
parietal lobe stroke
typically presents with attention deficits e.g. contralateral hemispatial neglect syndrome: where the patient does not pay attention to the side of the body opposite to the lesion.
