Question

what type of cells line the ventricles of the brain?
○ ependymal cells
○ neurons
○ epithelial cells
○ astrocytes

Explanation:

• Ependymal cells are a type of glial cell. They line the ventricles of the brain and the central canal of the spinal cord. Their function includes producing cerebro - spinal fluid (CSF) and helping in the circulation of CSF.
• Neurons are the basic functional units of the nervous system responsible for transmitting electrical and chemical signals. They are not the lining cells of the ventricles.
• Epithelial cells are a broad category of cells that form the covering of body surfaces and line body cavities. But the specific type lining the brain ventricles is ependymal (which is a specialized glial cell, not a general epithelial cell in the non - nervous system context).
• Astrocytes are another type of glial cell. Their functions include providing structural support, regulating the chemical environment around neurons, and participating in the blood - brain barrier. They do not line the ventricles.

Answer:

ependymal cells
