Cerebral White Matter and Lateral Ventricles Flashcards
What fibres does the white matter of the cerebral hemispheres consist of?
Association, commissural and projection fibers
What do long association fbers interconnect?
Lobes
What do short association fibres connect?
Adjacent areas within a lobe
What are examples of association bundles of the limbic system?
Cingulum, fornix and stria terminalis
What exchanges information between the left and right hemispheres?
Corpus callosum
Where do most projection fibres pass through?
Internal capsule
What fibres does the internal capsule consist of?
Thalamocortical and corticothalamic fibers
What is the largest of the 4 ventricles?
Lateral ventricle
What is the function of the lateral ventricle?
Production and flow of CSF fluid
How many types of axons are present in cerebral white matter?
Three
What are the axons present in cerebral white matter?
Association fibers, commissural fibers and projection fibers
Function of association fibres?
Confined to a hemisphere and connect one cortical are with another
Function of commissural fibres?
Connect the cortices of the two hemispheres
Where are commissural fibres located?
Mostly in the corpus callosum and remainder in the anterior commissure
Function of projection fibres?
Establish connections between the cortex and subcortical structures as the corpus striatum, thalamus, brain stem and spinal cord
