What Neuroglial cells produce CSF?
Ependymal cells: Ependymal cells line the spinal cord and ventricles of the brain. They are involved in creating cerebrospinal fluid (CSF).
Which Neuroglial cell helps circulate cerebrospinal fluid?
Ependymal cells are another glial subtype that line the ventricles of the CNS to help circulate the CSF. Oligodendrocytes are cells that wrap their process tightly around the fibers producing an insulating covering called myelin sheath. Schwann cells are similar in function to oligodendrocytes and microglial cells.
What are the four Neuroglial cells in the brain?
They are less electrically excitable than neurons and do not form chemical synapses. Based upon their appearance, function, and origin, four types of glial cells have been identified in the central nervous system: astrocytes, oligodendroglia, ependymal cells, and microglia.
What cells line the ventricles and produce CSF?
The choroid plexus is a complex network of capillaries lined by specialized cells and has various functions. One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain.
Where is CSF made?
Most CSF is formed in the cerebral ventricles. Possible sites of origin include the choroid plexus, the ependyma, and the parenchyma. Anatomically, choroid plexus tissue is floating in the cerebrospinal fluid of the lateral, third, and fourth ventricles.
What Neuroglial cell is most affected by multiple sclerosis?
Astrocytes are increasingly recognized as cells that critically contribute to the development of MS lesions. Previously, astrocytes were believed to react only at a late, post-inflammatory stage by forming a glial scar, but are now considered early and active players in lesion pathology (16, 17).
What is the function of CSF?
While the primary function of CSF is to cushion the brain within the skull and serve as a shock absorber for the central nervous system, CSF also circulates nutrients and chemicals filtered from the blood and removes waste products from the brain.
What cell makes CSF?
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. This creates the osmotic gradient, which drives the secretion of H(2)O.
What type of neurons are in the brain?
There are three classes of neurons: Sensory neurons carry information from the sense organs (such as the eyes and ears) to the brain. Motor neurons control voluntary muscle activity such as speaking and carry messages from nerve cells in the brain to the muscles. All the other neurons are called interneurons.
