CSF, Ventricles and Meninges Flashcards
What does the CNS develop from?
Neural tube
What are the chambers lined with?
Ependymal cells
What are ependymal cells?
Line chambers
Single epithelial-like cells
Partly responsible for CSF production
What does the ventricular system empty into?
Subarachnoid space
What is the role of CSF?
Lymph drainage of the brain
Auto-regulation of cerebral blood flow
Provides mechanical and immunological protection
Where is CSF mainly produced
Choroid plexus
Where else is CSF derived from?
Seepage from capillaries
Water from metabolism
Where does CSF circulate through?
Ventricular system and subarachnoid space
What is the choroid plexus?
Network of blood capillaries in each ventricle
What separates the ependyma of the ventricles from the surface?
Pia Matter
What are the ventricles?
4 CSF filled chambers in the brain
What does each cerebral hemisphere contain?
A lateral ventricle
Where does the lateral ventricle begin?
Inferior horn in temporal lobe
Which lobes does the lateral ventricle travel through?
Parietal and Frontal
Where does the lateral ventricle terminate?
Interventricular Foramina- each connects to the central third ventricle
Where does posterior horn of lateral ventricle protrude?
Occipital lobe
Where does anterior horn of lateral ventricle protrue
Further into frontal lobe
