Questions: make cerebrospinal fluid move cerebrospinal fluid around ependymal cells astrocytes microglia Schwann cells oligodendrocytes

The task is to fill in the blanks in the table with the correct cell types related to cerebrospinal fluid (CSF).

1. Make cerebrospinal fluid: The correct cell type for making cerebrospinal fluid is the choroid plexus epithelial cells. However, since this option is not provided in the list, the closest related cell type is ependymal cells. Ependymal cells line the ventricles of the brain and the central canal of the spinal cord and are involved in the production and circulation of CSF.

2. Move cerebrospinal fluid around: The correct cell type for moving cerebrospinal fluid around is ependymal cells. Ependymal cells have cilia that help in the circulation of CSF.

So, the completed table should look like this:

\begin{tabular}{l|l|} \hline make cerebrospinal fluid & ependymal cells \\ \hline & [Choose ] \\ \hline \begin{tabular}{l} move cerebrospinal fluid \\ around \end{tabular} & ependymal cells \\ \hline \end{tabular}

Explanation:

• Ependymal cells: These cells line the ventricles in the brain and the central canal of the spinal cord. They are involved in the production and circulation of cerebrospinal fluid.
• Astrocytes: These are star-shaped glial cells in the brain and spinal cord that support and protect neurons.
• Microglia: These are a type of glial cell that act as the main form of active immune defense in the central nervous system.
• Schwann cells: These cells are responsible for the myelination of peripheral nervous system neurons.
• Oligodendrocytes: These cells are responsible for the myelination of central nervous system neurons.

In summary, ependymal cells are responsible for both making and moving cerebrospinal fluid.
