Topography of Cerebral hemispheres Flashcards
The large surface are of the human cerebral cortex results in a pattern of what?
Gyri and sulci
How many lobes are recognised in each cerebral hemisphere?
Five
What separates the parietal from the occipital lobe on the medial surface of the hemisphere?
Parieto-occipital sulcus
In the occipital lobe, what is the site of the primary visual cortex?
Calcarine sulcus
In the parietal lobe, what corresponds to the first general somatic sensory area?
Postcentral gyrus
Where is the central sulcus located between?
Parietal and frontal lobes
What separates the frontal and parietal lobes form the temporal lobe?
Lateral sulcus
What is a landmark for part of the corpus striatum?
The insular lobe located in the floor of the lateral sulcus
How many rami does the lateral sulcus divide into?
Three
What are the rami of the lateral sulcus?
Posterior, anterior and ascending
Where does the anterior and ascending rami project into?
Frontal lobe
What tissue separates the hemispheres?
Longitudinal fissure
What is the dural partition that extends into the fissure?
Falx cerebri
What fissure intervenes between the cerebral hemispheres above and the cerebellum, midbrain and diencephalon below?
Transverse cerebral fissure
What lobe occupies the entire area in front of the central sulcus and above the lateral sulcus on the lateral surface?
Frontal lobe
