Answer:
<u>Astrocytes</u> are the neuroglia, which help to regulate the reuptake of neurotransmitters from neural tissue.
Cell bodies of unipolar neurons are insulated from adjacent cell bodies by <u>satellite cells</u>.
The ventricles of the brain are lined with <u>ependymal cells</u>, which form an epithelial layer that is permeable to cerebrospinal fluid.
The macrophages of the Central Nervous System, which function to remove foreign microorganisms, are called<u> microglia</u>.
The myelin sheath of the Central Nervous System is formed by <u>oligodendrocytes</u>.
Axons of unipolar neurons are insulated by <u>Schwann cells</u>, which increase the speed of the electrical impulse.
Explanation:
The neuroglia cells are a group of specialized cells that are in the Central and Peripheral Nervous System.
Astrocytes are star-shaped cells that maintain homeostasis in the nervous tissue. They also are part of the blood-brain barrier controlling what can enter the brain and whatnot.
Satellite cells are in the Peripheric Nervous System. They are around neurons and provide nutrients and insulation to neurons.
Ependymal cells are in the Central Nervous System. They line the ventricles and spinal cord's central canal. They are the ones that help in the production and circulation of the cerebrospinal fluid (CSF). They are part of the blood-cerebrospinal fluid barrier, keeping the cerebrospinal fluid clean, and they also absorb the CSF.
The microglia are the macrophages of the Central Nervous System. They phagocytize any pathogen that they detect in the CNS, protecting the neurons.
The myelin sheath is formed by the oligodendrocytes in the CNS and by the Schwann cells in the PNS. Their function is to insulate the axons so that the electrical impulse can travel through them.
