Answer: The correct match between the description of the neuroglia and the cell type is:
A) Phagocytes; Supportive function - Microglia
B) Form myelin in CNS - Oligodendrocytes
C) Covers the choroid plexus; Lines space in the brain (ventricles) - Ependymal cells
D) Found between neurons and blood vessels (blood-brain barrier); Regulate ion concentration in nervous tissue - Astrocytes
Step-by-step explanation:

D) Found between neurons and blood vessels (blood-brain barrier); Regulate ion concentration in nervous tissue - Astrocytes
Step-by-step explanation:
1) Microglia: Microglia are phagocytes in the central nervous system (CNS). They have a supportive function by removing cellular debris, pathogens, and dead neurons from the brain and spinal cord.
2) Oligodendrocytes: Oligodendrocytes are responsible for forming myelin in the CNS. Myelin is a fatty substance that wraps around nerve fibers, providing insulation and allowing for faster transmission of electrical impulses.
3) Ependymal cells: Ependymal cells cover the choroid plexus, which produces cerebrospinal fluid (CSF), and line the ventricles (spaces) in the brain. They help circulate CSF and provide a barrier between the CSF and brain tissue.
4) Astrocytes: Astrocytes are found between neurons and blood vessels, contributing to the blood-brain barrier. They regulate the ion concentration in nervous tissue, maintaining a stable environment for neuronal function.
