The Cerebral Hemispheres Flashcards
What is the name of the small dips in the surface of the cerebrum?
Sulci
What is the name of the larger dips on the surface of the cerebrum?
Fissure
What is the name of the cavity in each ventricle?
Lateral ventricle
What is the name of the large dip down the centre of the cerebrum
Medial longitudinal fissure
What is the faux cerebri?
The fold of the dura as it dips into the median longitudinal fissure
What is the innermost meninge of the brain?
Pia matter
What dip separates the temporal lobe form the frontal lobe laterally?
Lateral sulcus
What dip continues from the lateral sulcus over the superior part of the cerebrum to join the other lateral sulcus and separate the parietal and frontal lobes coronally?
Central sulcus
What is the area just anterior of the central sulcus not he surface of the cerebrum?
Precentral gyrus
What is the area just posterior to the central sulcus on the surface of the cerebrum?
Postcentral gyrus
What dip can be seen when the brain is cross-sectioned in the midline separating the parietal and occipital lobes?
Pareto-occipital sulcus
What is the c-shaped structure or bridge in the centre of the brain?
Corpus collosum
What is the dip that runs around and in line with the corpus colloum in the midline orientation?
Cingulate sulcus
What is the insula?
The insula, part of the temporal lobe - can only be seen on resection of the frontal and parietal lobes
What are the sections of the frontal lobe?
superior, inferior, inferior frontal gyri
What are the sections of the parietal lobe?
Superior, inferior parietal lobule
What are the sections of the temporal lobe?
Superior, middle, inferior temporal gyri
What Brodmann’s Areas?
52 sections of the cortex divided on th e basis of histology that are used to describe locations on the cortex
In basic terms what is the motor area of the brain?
Anterior part of cerebrum
