Final answer:
Glial cells are nerve cells that conduct impulses (Option E). Glial cells, or neuroglia, are supportive cells in nervous tissue that maintain the environment for neurons in the central and peripheral nervous systems. They include astrocytes, oligodendrocytes in the CNS, and Schwann cells in the PNS, crucial for myelination and overall neural support.
Step-by-step explanation:
Glial cells, also known as neuroglia, are a vital component of nervous tissue that provide support and protection for neurons in both the central nervous system (CNS) and the peripheral nervous system (PNS).
In the CNS, different types of glial cells include astrocytes, oligodendrocytes, microglia, and ependymal cells. Astrocytes are crucial for providing nutrients to neurons, maintaining the extracellular environment, and offering structural support.
Oligodendrocytes are responsible for forming the myelin sheath, which insulates axons to facilitate the efficient transfer of electrical nerve impulses.
Additionally, in the PNS, Schwann cells also form the myelin sheath around axons, while satellite cells supply nutrients and structural support. Unlike glial cells, neurons are the actual nerve cells capable of conducting impulses throughout the nervous system.
The synergistic relationship between glial cells and neurons is essential for the proper functioning of the nervous system, ensuring the transmission of electrochemical signals and overall neural communication.
Hence, the correct answer is Option E.
