The classic view has been that a so-called subdural space is located between the arachnoid and dura and that subdural hematomas or hygromas are the result of blood or cerebrospinal fluid accumulating in this (preexisting) space.

Is there cerebrospinal fluid in the subdural space?
The subdural space is a poten- tial thin space located between the inner dura mater and the arachnoid. The film of fluid in the subdural space is not CSF. The dura mater is also called the pachy- meninx and the arachnoid and pia mater com- prise the leptomeninges.
What space is cerebrospinal fluid found?
The cerebrospinal fluid (CSF) is contained in the brain ventricles and the cranial and spinal subarachnoid spaces. The mean CSF volume is 150 ml, with 25 ml in the ventricles and 125 ml in subarachnoid spaces.
Is there fluid in subdural space?
The subdural space is a potential intracranial space situated between the arachnoid and dura. Fluid can collect in the subdural space and in the subarachnoid space.
Where is CSF fluid found?
Cerebrospinal fluid (CSF) is a clear, colorless liquid found in your brain and spinal cord. The brain and spinal cord make up your central nervous system.
Is subdural space the same as arachnoid space?
The potential space between the arachnoid and dura is called the subdural space and according to some authors, it contains a very thin layer of fluid. The space between the arachnoid and pia is called the subarachnoid space and it is filled with the cerebrospinal fluid (CSF).
What does the subdural space contain?
The subdural space (or subdural cavity) is a potential space that can be opened by the separation of the arachnoid mater from the dura mater as the result of trauma, pathologic process, or the absence of cerebrospinal fluid as seen in a cadaver.
Where is the cerebrospinal fluid found quizlet?
Cerebrospinal fluid (CSF) is found between the arachnoid and pia mater of the brain and spinal cord in the space called the subarachnoid space. The lateral ventricles (first and second ventricles) extend into the cerebra hemispheres and occupy part of the frontal, temporal, and occipital lobes.
What space does not contain CSF?
The dural sinus does not contain CSF.
What is in cerebrospinal fluid?
As a result, CSF contains a higher concentration of sodium and chloride than blood plasma, but less potassium, calcium and glucose and protein. Choroid plexuses also secrete growth factors, iodine, vitamins B1, B12, C, folate, beta-2 microglobulin, arginine vasopressin and nitric oxide into CSF.
How does CSF enter the subarachnoid space?
CSF flows from the lateral ventricle to the third ventricle through the interventricular foramen (also called the foramen of Monro). CSF then flows into the subarachnoid space through the foramina of Luschka (there are two of these) and the foramen of Magendie (only one of these).
Is CSF found in the central canal?
The central canal is part of a system of cerebrospinal fluid (CSF) cavities that includes the cerebral ventricle, aqueduct of Sylvius, and fourth ventricle (Figures 3-4) [2].
