Read each question carefully and provide your best answer. This worksheet assesses your understanding of neuroglial cells and their functions in the nervous system.
1. Which type of neuroglial cell is responsible for forming the myelin sheath around axons in the Central Nervous System (CNS)?
Astrocyte
Schwann cell
Oligodendrocyte
Microglia
2. Which neuroglial cells are phagocytic and act as the immune cells of the CNS?
Ependymal cells
Astrocytes
Microglia
Satellite cells
3. cells line the ventricles of the brain and the central canal of the spinal cord, producing and circulating cerebrospinal fluid.
4. In the Peripheral Nervous System (PNS), cells are responsible for forming the myelin sheath around axons.
5. Astrocytes play a crucial role in maintaining the barrier, regulating the chemical environment of the CNS.
6. Neuroglial cells participate directly in the transmission of nerve impulses.
True
False
7. Satellite cells in the PNS have similar functions to astrocytes in the CNS.
True
False
Match each neuroglial cell type with its primary function.
8. Astrocyte
