1

what constitutes as the forebrain?

the diencephalon and the cerebral hemispheres

2

what is the function of the forebrain?

higher level processing of information - perception, analysis, interpretation, integration, storage, planning

3

which part of the neural tube develops into the forebrain?

the prosencephalon

4

what is the thalamus?

a collection of nuclei

5

which ventricle is wedged between each thalamus?

the third ventricle

6

what is the role of the hypothalamus?

autonomic and endocrine function

7

what is role of epithalamus

includes the pineal gland and secretes melatonin

8

what do the association fibres link?

association fibres link with in each hemisphere

9

what type of fibre link within each hemisphere

association fibres

10

what do the commissural fibres link?

the two hemispheres

12

what are projection fibres?

they carry information to or from the hemispheres e.g the internal capsule

WHERE IS THE 4th ventricle located?

between the cerebellum, pons and medulla

17

where is CSF produced?

the choroid plexus

18

CSF

19

what is the function of CSF?

brain and spinal cord float to reduce traction
cushioning effect to dampen trauma
removes metabolites from CSF
provides stable environment
