What fibres does the white matter of the cerebral hemispheres consist of?

A

Association, commissural and projection fibers

2
Q

What do long association fbers interconnect?

A

Lobes

3
Q

What do short association fibres connect?

A

Adjacent areas within a lobe

4
Q

What are examples of association bundles of the limbic system?

A

Cingulum, fornix and stria terminalis

5
Q

What exchanges information between the left and right hemispheres?

A

Corpus callosum

6
Q

Where do most projection fibres pass through?

A

Internal capsule

7
Q

What fibres does the internal capsule consist of?

A

Thalamocortical and corticothalamic fibers

8
Q

What is the largest of the 4 ventricles?

A

Lateral ventricle

9
Q

What is the function of the lateral ventricle?

How many types of axons are present in cerebral white matter?

A

Three

11
Q

What are the axons present in cerebral white matter?

A

Association fibers, commissural fibers and projection fibers

12
Q

Function of association fibres?

A

Confined to a hemisphere and connect one cortical are with another

13
Q

Function of commissural fibres?

A

Connect the cortices of the two hemispheres

14
Q

Where are commissural fibres located?

A

Mostly in the corpus callosum and remainder in the anterior commissure

15
Q

Function of projection fibres?

A

Establish connections between the cortex and subcortical structures as the corpus striatum, thalamus, brain stem and spinal cord

16
Q

Where do most afferent projection fibres originate?

A

Thalamus

Q

What fills the lateral ventricles?

A

CSF

Q

What lines the lateral ventricles?

A

Ependymal cells
