A drainage cell or oligodendrocyte is a type of glial cell that is found in the white matter of the brain and spinal cord and in the meninges. Oligodendrocytes can vary in shape and size, but in general they have a round shape and the presence of an intracellular cavity, which
A drainage cell is a type of oligodendrogliocyte, which is characterized by a rounded shape and the presence of cavities inside the cell called drainage canaliculi. These tubules serve to remove excess fluid from the nerve tissue.
Drainage cells have a diameter of about 10-20 microns and are located in the central part of the nervous tissue, where they form a network capable of draining fluid from nearby neurons. They are also involved in the formation of the myelin sheath around nerve fibers, which improves the speed of transmission of nerve impulses.
Drainage cells have several features that distinguish them from other cell types in the nervous system. Firstly, they contain special tubules inside themselves that allow them to remove fluid from the environment. In addition, drainage cells have the ability to regenerate, which makes them very important for maintaining the normal functioning of the nervous system.
However, despite all their advantages, drainage cells can also cause problems if they are used in excess. An excess of these cells can lead to cerebral edema, which is a serious condition that requires medical attention.
Thus, drainage cells play an important role in the functioning of the nervous system, but their excess can lead to serious problems. Therefore, it is important to monitor the state of the nervous system and, if necessary, take measures to prevent excessive formation of drainage cells.
