forebrain and ventricles Flashcards
what constitutes as the forebrain?
the diencephalon and the cerebral hemispheres
what is the function of the forebrain?
higher level processing of information - perception, analysis, interpretation, integration, storage, planning
which part of the neural tube develops into the forebrain?
the prosencephalon
what is the thalamus?
a collection of nuclei
which ventricle is wedged between each thalamus?
the third ventricle
what is the role of the hypothalamus?
autonomic and endocrine function
what is role of epithalamus
includes the pineal gland and secretes melatonin
what do the association fibres link?
association fibres link with in each hemisphere
what type of fibre link within each hemisphere
association fibres
what type of fibres link between the two hemispheres?
commissural
what do the commissural fibres link?
the two hemispheres
what are projection fibres?
they carry information to or from the hemispheres e.g the internal capsule
what does the globes pallid us and the putamen form?
the lentiform nucleus
which lies most lateral? the globus pallidus or the putamen?
putamen
which two ventricles does the cerebral aqueduct connect?
the third and 4th ventricle
WHERE IS THE 4th ventricle located?
between the cerebellum, pons and medulla
where is CSF produced?
the choroid plexus
what does the choroid plexus produce?
CSF
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
where is the choroid plexus?
lateral ventricle
where is CSF recycled?
the superior sagittal sinus and rest of dural sinuses
