Question

What type of glial cell produces cerebrospinal fluid (CSF)?

A. Astrocyte
B. Microglia
C. Ependymal cell
D. Oligodendrocyte

Answer 1

The ependymal cells are responsible for filtering blood to produce cerebrospinal fluid (CSF) in the brain's ventricles and the spinal cord's central canal.

Step-by-step explanation:

The type of glial cell that is responsible for producing cerebrospinal fluid (CSF) is the ependymal cell. Ependymal cells line the ventricles of the brain and the central canal of the spinal cord, which are spaces through which CSF flows. These cells filter blood at the choroid plexus to produce CSF, which is crucial in providing a protective cushion for the brain and spinal cord and maintaining the appropriate chemical environment.

Astrocytes are responsible for maintaining the chemical environment around neurons and regulate the blood-brain barrier. However, they are not responsible for the production of CSF. Microglia serve as the immune cells within the central nervous system. Oligodendrocytes produce myelin sheath around neurons in the CNS but do not produce CSF. Therefore, the correct answer to the question is C. Ependymal cell.

Answer 2

Ependymal cells are the type of glial cell responsible for filtering blood to produce cerebrospinal fluid (CSF) at the choroid plexus.The correct option is C, Ependymal cell.

Step-by-step explanation:

Ependymal cells are the type of glial cell responsible for filtering blood to produce cerebrospinal fluid (CSF) at the choroid plexus.

Within the central nervous system (CNS), which includes the brain and spinal cord, there are different types of glial cells that support the neurons. These include astrocytes, oligodendrocytes, microglia, and ependymal cells.

Among these, ependymal cells are specialized to line the ventricles of the brain and spinal cord and are responsible for producing CSF. The choroid plexus, found within each ventricle, filters blood and selects specific components to create CSF, which circulates throughout the CNS.Option C, Ependymal cell is correct option.
