Cererbrum into Flashcards
The cerebrum is derived embryologically from?
The telencephalon
The cerebrum is the
largest part of the forebrain which reaches the greatest degree of development in the human brain
The cerebral cortex is located ________
superficially
The cerebral cortex is located superficially and consists of
cortical grey matter (i.e. nerve cell bodies) that is highly convoluted to form a complex pattern of ridges (gyri; singular, gyrus) and furrows (sulci; singular, sulcus)
The subcortical grey matter is located within the
White matter
The subcortical grey matter is located within the white matter and consists of the
thalamus and basal ganglia
The cerebral white matter is located deep to the cortex and consists of
nerve fibers (axons)
Most of the nerve fibres running between the cortex and subcortical structures are condensed, deep within the hemisphere, into a
broad sheet, the internal capsule
Between the internal capsule and the cortical surface, fibres radiate in and out, to produce a
fan-like arrangement, the corona radiata
The cerebrum houses the _________ ventricles
Lateral ventricles
Two hemispheres are separated by the
longitudinal fissure
Corpus callosum is located in the depths of the fissure and is an enormous sheet of commissural nerve fibres which run between corresponding areas of the two cortices
Name the three surfaces of the cortex
- Superolateral
- Medial
- Inferior
Name the three borders of the cortex
- Superomedial
- Inferolateral
- Inferomedial
