How is CSF produced and reabsorbed?
The CSF from the subarachnoid space is eventually reabsorbed through outpouchings into the superior sagittal sinus (SSS) known as the arachnoid granulations. Arachnoid granulations act as an avenue for CSF reabsorption into the blood circulation through a pressure-dependent gradient.
Where is CSF produced and absorbed?
choroid plexus
According to the traditional understanding of cerebrospinal fluid (CSF) physiology, the majority of CSF is produced by the choroid plexus, circulates through the ventricles, the cisterns, and the subarachnoid space to be absorbed into the blood by the arachnoid villi.
How does cerebrospinal fluid get absorbed?
It has traditionally been thought that CSF is absorbed through tiny, specialized cell clusters called arachnoid villi near the top and midline of the brain. The CSF then passes through the arachnoid villi into the superior sagittal sinus, a large vein, and is absorbed into the bloodstream.
What is the circulation of cerebrospinal fluid?
Cerebrospinal fluid flow
Secretion | Choroid plexus (lateral, third and fourth ventricles), interstitial space and dura of the nerve root sleeves |
---|---|
Circulation | Lateral ventricle → third ventricle → fourth ventricle → central canal of spinal cord → subarachnoid space |
What produced CSF?
choroid plexus epithelium
CSF is produced mainly by the choroid plexus epithelium and ependymal cells of the ventricles and flows into interconnecting chambers; namely, the cisterns and the subarachnoid spaces.
Where does the cerebrospinal fluid CSF circulate quizlet?
CSF flows from the subarachnoid space at the base of the brain rostrally over the cerebral hemispheres or down the spinal cord.
What is CSF and its functions?
Cerebrospinal fluid (CSF) is an ultrafiltrate of plasma contained within the ventricles of the brain and the subarachnoid spaces of the cranium and spine.[1] It performs vital functions, including providing nourishment, waste removal, and protection to the brain.[2] Adult CSF volume is estimated to be 150 ml, with a …
What is the order that cerebrospinal fluid will take from creation to reabsorption?
Normal route of CSF from production to clearance is the following: From the choroid plexus, the CSF flows to the lateral ventricle, then to the interventricular foramen of Monro, the third ventricle, the cerebral aqueduct of Sylvius, the fourth ventricle, the two lateral foramina of Luschka and one medial foramen of …
Where does the cerebrospinal fluid circulate quizlet?
Where is cerebrospinal fluid produced?
CSF is secreted by the CPs located within the ventricles of the brain, with the two lateral ventricles being the primary producers. CSF flows throughout the ventricular system unidirectionally in a rostral to caudal manner.
What produces CSF fluid?
CSF is produced mainly by a structure called the choroid plexus in the lateral, third and fourth ventricles. CSF flows from the lateral ventricle to the third ventricle through the interventricular foramen (also called the foramen of Monro).
What secretes cerebrospinal fluid?
the choroid plexus
The epithelial cells of the choroid plexus secrete cerebrospinal fluid (CSF), by a process that involves the movement of Na(+), Cl(-) and HCO(3)(-) from the blood to the ventricles of the brain.
