Verified step by step guidance

Step 1: Understand the function of each cell type listed in the options. Astrocytes are glial cells that provide support and maintain the environment around neurons, but they do not transmit electrical impulses.

Step 2: Learn about microglia. Microglia are immune cells of the central nervous system that act as macrophages, cleaning up debris and protecting against pathogens. They are not involved in transmitting electrical impulses.

Step 3: Examine oligodendrocytes. Oligodendrocytes are glial cells responsible for producing the myelin sheath that insulates axons in the central nervous system, aiding in faster transmission of electrical signals, but they do not directly transmit impulses.

Step 4: Focus on neurons. Neurons are the primary cell type responsible for transmitting electrical impulses in nervous tissue. They have specialized structures such as axons and dendrites to facilitate this function.

Step 5: Conclude that neurons are the correct answer because they are the only cell type listed that directly transmits electrical impulses, which is their primary role in the nervous system.
