Question

match the description of the neuroglia with the correct cell type.
phagocytes; supportive function
form myelin in cns
covers the choroid plexus; lines space in the brain (ventricles)
found between neurons and blood vessels (blood - brain barrier); regulate ion concentration in nervous tissue

Explanation:

• Microglia are phagocytes in the central nervous system (CNS) and have a supportive function.
• Oligodendrocytes form myelin in the CNS.
• Ependymal cells cover the choroid plexus and line the ventricles (spaces in the brain).
• Astrocytes are found between neurons and blood vessels (involved in the blood - brain barrier) and regulate ion concentration in nervous tissue.

Answer:

1. Phagocytes; supportive function - Microglia
2. Form myelin in CNS - Oligodendrocytes
3. Covers the choroid plexus; lines space in the brain (ventricles) - Ependymal cells
4. Found between neurons and blood vessels (blood - brain barrier); regulate ion concentration in nervous tissue - Astrocytes
