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.
Where is CSF made quizlet?
CSF is produced by the choroid plexus in the ventricles. CSF flows from the 3rd ventricle through the cerebral aqueduct into the 4th ventricle. CSF then flows into the subarachnoid space by passing through the paired lateral apertures or the single median aperture and into the central canal of the spinal cord.
What is CSF made of quizlet?
CSF IS MADE FROM THE CHOROID PLEXUS AND LINED WITH THE EPENDYMAL CELLS.
What is cerebrospinal fluid class 10?
Answer: Cerebrospinal fluid is the fluid found in the cavities of brain, central canal of spinal cord and in between arachnoid and pia mater. Function: It prevents the brain from mechanical shocks.
How is a CSF sample processed?
Use a sterile syringe and needle to inoculate 0.5-1.0 ml of CSF into the T-I medium. The remaining CSF should be kept in the collection tube. It should not be refrigerated, but should be maintained at room temperature (20-25°C) before Gram staining and other tests.
What part of the brain produces cerebrospinal fluid quizlet?
A clear colorless liquid formed in the VENTRICLES of the BRAIN by SECREATION from the CHOROID PLEXUS. CSF IS MADE FROM THE CHOROID PLEXUS AND LINED WITH THE EPENDYMAL CELLS.
What is cerebrospinal fluid composed of quizlet?
What would you normally find in cerebrospinal fluid?
The analysis of CSF obtained by lumbar puncture gives clues to various disease processes. In healthy individuals the fluid is normally crystal clear and colourless. However, it will contain blood if subarachnoid hemorrhage has occurred. The presence of white blood cells or bacteria is indicative of infection.
What are the characteristics of normal cerebrospinal fluid?
Pressure of the CSF can be measured when opening (starting) and closing (finishing) the collection.
What produces cerebrial spinal fluid?
Medical Definition of Cerebrospinal fluid. Abbreviated CSF. CSF is produced by the choroid plexus, a series of infolded blood vessels that project into the cerebral ventricles, and it is absorbed into the venous system. If production exceeds absorption, CSF pressure rises, and the result is hydrocephalus.
What are the chambers within the brain that contain cerebrospinal fluid called?
Meninges. The middle layer, the arachnoid mater, contains cerebrospinal fluid, arteries, veins, and cranial nerve roots. It also secures the dura to the innermost layer, the pia mater, a delicate membrane that clings to the contours of the brain, thereby distributing the forces that suspend the brain within the skull.
