What is Ependy?

Ependyma is a cell membrane that surrounds the chambers of the brain and spinal cord. Usually it consists of ependymal cells that have projections similar to hair called cilia, which can help move cerebrospinal fluid (CSF) throughout the column and brain. In Ependy there are also cells called tanycytes, which often associate with nerve cells and can help move different types of molecules to the brain and brain. These cells can control the functions of the gland pituitary gland and may also affect the nitric oxide synthesis to control neurological activity and blood flow. Structures called microvilli in the membrane can absorb CSF.

Ependymal cells are associated with different small organs, including the plexuses of choroids that exclude cerebrospinal fluid, and the poststerem area at the end of the fourth chamber of the brain, which is usually dominated by microvilli. Ependy is usually associated with the Pineal gland responsible for secretion of melatonin, the rear pituitary gland and other small organs in the brain. A membrane that acts as a physical barrier canAlso block potentially hazardous materials in CSF to cause brain damage. It often filters toxins before any molecules or fluids can pass.

The filtration process is usually supported by enzymes that allow the transport of molecules. Toxins are blocked and substances called amines, which include serotonin and dopamine, can be deactivated by an enzyme called monoamine oxidase located in the epends. Tanycytes that are associated with nerve fibers sometimes control the levels of pituitary gland and are often present in a part of the brain called hypothalamus. There are also places where a substance that regulates water and electrolytes in the brain can also be bound.

Some medical studies suggest that there may be stem cells in Ependy. The neural cells of this type think some scientists think that he may restore hearing when they are implanted in Kochle and in the organ in the inner ear. Medical problems associated with the membrane can zHRhn inflammation, a tumor called ependymom and a type of tumor that comes from choroid plexes.

Ependyma could also be involved in a neurological recovery after brain damage or other parts of the central nervous system. A substance called fibroblastic growth factor can be regulated by membrane cells and activated after trauma. This protective layer of cells are therefore regulated by neurological activity, blood flow and the ability to regenerate the nervous system.
