Match the neuroglial cell with its function.
a. influence function of blood-brain barrier
b. macrophages in cns
c. produce cerebrospinal fluid
d. form myelin sheath around axons in cns
e. form myelin sheath around part of the axon in the pns ependymal cells

A)  Astrocytes

B) Phagocytes

C)  Ependyma cells (ependymocytes)

D) Oligodendrocytes

E)   Schwann cells

Explanation:

A)The Astrocytes are in charge of the biochemical support of endothelial cells that form the blood-brain barrier and have an important participation in repairing and scarring process of the brain after and following internal traumatic injuries.

B) Phagocytes are white blood cells that combat anything without the type of proteins specific to healthy body cells on its surface, they are found in many parts and systems of the body, Central nervous system included.

C) The Ependyma cells serve as a reservoir for neuroregeneration, however, they are strongly involved in the production of cerebrospinal fluid. Groups of them get together and are a part of a structure called the choroid plexus, which produces the Cerebrospinal fluid.

D) One of the Oligodendrocyte's main functions is to provide support to axons in the central nervous system, however, they are the main responsible for the Myelin sheats production.

E) The Schwann cells function are pretty similar compared to the Oligodendrocytes, however, these are located in the peripheral nervous system, covering the axons with myelin sheaths, its name is in honor to the German physiologist Theodor Schwann.
