WVSOM -- Medical Neuroscience -- Ventricles

What foramen are on the lateral sides of the fourth ventricle and where do they lead? Foramen of Luschke that open to the sub-arachnoid space
What is the central opening of the 4th ventricle and where does it go? Foramen of magendie which provides communication
Where is the 4th ventricle? on the dorsal surface of teh brain stem beneath the cerebellum
What does teh third ventricle separate? left and right diencephalon
How does the 3rd ventricle connect to the 4th ventricle? cerebral aqueduct
Where does teh cerebral aqueduct pass thru? the length of the midbrain
What is the rostral border of the 3rd ventricle? lamina terminalis
What does the lateral ventricle contain? large amounts of chorid plexus
Describe the production of CSF predominantly in the choroid plexus predominently in lateral ventricles. capilaries in the plexus are large, thin and fenestrated. Na+ is secreted by choroid peithelial cells into the CSF follwed by passive meovement of water from teh chorid capillaries
How much CSF is produced a day? 400-500ml
How much total CSF is in the body at a time? 150ml
Describe the flow of CSF flows from the lateral vetnricle thru the interventricular foramen into the 3rd ventricle and then into the fourth ventricle via the cerebral aqueduct. CSF leaves teh ventrices thru the 3 aperatures of the 4th ventricle to enter the subarachnoid space
How does most CSF leave the 4th ventricle? median apperature
How is CSF reabsorbed? reabsorbed into the venous system by passing into thedural venous sinuses. along the sinuses are aracnoid villi which consist of invatination of arachonid mater where reabsorption occurs.
What does reabsoprtion occur in the arachonid villi? there is higher hydrostatic prssure in the subarachnoid space than the sinus lumen
What is communicating hydrocephalus? impaired CSF reabsorption, obstruction of flow in SAS or rarely excess CSF production
What is non-communicating hydrocephalus? obstruction of flow within the ventricular system. Common at narrow poitns such as foramen or aqueduct
What are symptoms of hyrdocephalus? headach, N/V, cognitive impairment, decreased LOC, papilledema and decreased visual function
