The correct answer to fill in the blank is: glial cells.
Explanation:
<u>Glial cells are the other type of cells aside from neurons that are present in the nervous system. </u>
Glial cells are present both in the Central Nervous System and the Peripheral Nervous System, but in each of these anatomical divisions, the glial cells differ. For example, in the <u>Central Nervous System</u> there are oligodendrocytes (form myelin), astrocytes (provides nutrition for the neurons, maintains the ionic balance, repairs the tissue after damage, and forms the blood-brain barrier), ependymal cells (produces cerebrospinal fluid), and microglia (a specialized macrophage); while in the <u>Peripheral Nervous System</u> there are only Schwann cells (form myelin) and satellite cells (provide nutrients for the neurons).
