In the brain we have small protrusions of the arachnoid and subarachnoid space into the venous system. These protrusions are called arachnoid villi or arachnoid granulations and they allow for drainage of CSF into the venous system. Another source of CSF drainage is the lymphatic system.

What is the area in which cerebrospinal fluid collects before its return to the blood?
CSF is returned to the blood stream through lateral ventricles
What contains a delicate network of collagen and elastin fibers through which cerebrospinal fluid circulates?
The arachnoid and sub-arachnoid spaces.
Where is cerebrospinal fluid?
Cerebrospinal fluid is found in the ventricles of the brain (which are inside the cerebral cortexes and the cerebellum) as well as flowing around the meninges of the brain and spinal cord (on the outside of both structures).
Where is the intrathecal space located?
The intrathecal space is located between the arachnoid and the pia mater of the brain and spinal cord It is also known as the subarachnoid space.
What is a subarachnoid heamorraghe?
A subarachnoid hemorrhage is an abnormal and very dangerous condition in which blood collects beneath the arachnoid mater, a membrane that covers the brain. This area, called the subarachnoid space, normally contains cerebrospinal fluid. The accumulation of blood in the subarachnoid space can lead to stroke, seizures, and other complications
What does CSF consist of?
subarachnoid space
What procedure involves the use of needle to remove CSF from the subarachnoid space?
Lumbar puncture
Where is the csf found in relation to the meninges?
The CSF is found beneath the third layer of meninges, the Arachnoid matter, in an area called the Subarachnoid Space.
What diagnostic test involves collecting a sample of CSF?
A lumbar puncture (spinal tap) is the procedure where a needle is inserted into the subarachnoid space to draw a sample of cerebrospinal fluid (CSF).
What is the area in which cerebrospinal fluid collects before its return to the blood?
CSF is returned to the blood stream through lateral ventricles
What fluid is contained in the arachnoid and pia mater?
Well, technically between the arachnoid mater and the pia mater is the SUBARACHNOID space. This is where the cerebrospinal fluid (CSF) is located.
Which procedure involves the use of a needle to remove CSF from the subarachnoid spaces?
Lumbar puncture
What is the subarachnoid space?
The space between the arachnoid and pia mater is called the subarachnoid space
What contains a delicate network of collagen and elastin fibers through which cerebrospinal fluid circulates?
The arachnoid and sub-arachnoid spaces.
Where does CSF circulate and where is it returned to the blood?
CSF is cerebrospinal fluid . It is a colorless fluid found in the brain and spine. It is formed in the lateral ventricles from where it circulates through the interventricular foramens into the third ventricle and finally into the fourth ventricle.
What is the innermost mennix around the spinal cord?
Pia Matter * Thin, innermost mennix composed of collagen and elastic fibers. *vascularized *cerebrospinal fluis (CSF) is found in the subarachnoid space between the pia matter and arachnoid
Where does cerebrospinal fluid flows?
subarachnoid space
