Ependymal cells are special cells that line the spaces in our brain and the spinal cord. They help in important ways, especially with a fluid called cerebrospinal fluid (CSF). Let’s break down how these cells work:
Making CSF: Ependymal cells help create cerebrospinal fluid. In a part of the brain called the choroid plexus, these cells produce CSF. This fluid is really important for how our brain works. Adults make about 500 mL of CSF every day, which is around 25 mL each hour.
Moving CSF: Ependymal cells have tiny hair-like structures called cilia on their surface. These cilia move in sync to help push CSF around the brain. This movement is key because it helps deliver nutrients to the brain and remove waste.
Protective Barrier: Ependymal cells act as a barrier between CSF and the brain itself. They control what can pass between the two, which is important for keeping everything balanced in the brain and spinal cord.
Supporting New Brain Cells: In some areas, ependymal cells can act like stem cells, which means they can help make new brain cells. This is important for repairing the brain and supporting its growth.
In short, ependymal cells are crucial for keeping CSF levels stable and helping the central nervous system stay healthy.
