Final answer:
The incorrect statement about neuroglial cells is that they conduct electrical impulses. Neuroglial cells support and maintain the nervous system but do not conduct electrical signals like neurons. They have a variety of functions including forming myelin sheaths and providing nutrients and structural support to neurons. The answer is option A.
Step-by-step explanation:
The statement regarding neuroglial cells that is not true is that neuroglial cells conduct electrical impulses. Neuroglial cells, also known as glial cells or simply glia, are fundamental in the support and maintenance of the nervous system, but they do not conduct electrical impulses like neurons do.
Instead, they have a variety of other functions such as forming myelin sheaths around axons to insulate them and increase the speed of nerve impulse transmission, providing support and nutrients to neurons, maintaining the extracellular environment, and playing a role in immune defense within the central nervous system (CNS) and the peripheral nervous system (PNS). There are several types of glial cells, including astrocytes, oligodendrocytes, ependymal cells, and microglial cells in the CNS, as well as Schwann cells and satellite cells in the PNS, each serving specific functions within the nervous system.
