Which glial cell produces and helps circulate cerebrospinal fluid?

The glial cell that produces and helps circulate cerebrospinal fluid is the ependymal cell.

Here are the steps to answer this question:

1. Understand the question: The question is asking about a specific type of glial cell that has the function of producing and circulating cerebrospinal fluid.

2. Recall the information: Glial cells are non-neuronal cells in the central nervous system. There are several types of glial cells, including astrocytes, oligodendrocytes, microglia, and ependymal cells.

3. Identify the correct glial cell: Among these, ependymal cells are the ones that produce and help circulate cerebrospinal fluid. They line the ventricles of the brain and the central canal of the spinal cord.

4. Answer the question: Therefore, the answer to the question is ependymal cells.
