Glial Cells

Question 1

The two basic cell types found in the central nervous system are neurons and support cells (glial cells).

Types of glial cell include:-

Answer 1

Macroglia (Astrocytes, and oligodendrocytes)
Ependymal cells
Microglia

Question 2

Astrocytes

Answer 2

Astrocytes have numerous functions including structural support, repair of nervous tissue, providing nourishment to neurons, contributing to the blood brain barrier, neurotransmission, and vasomodulation. There are two main types, protoplasmic and fibrous.

Question 3

Oligodendrocytes

Answer 3

Oligodendrocytes are responsible for the formation of myelin sheaths.

Question 4

Ependymal cells

Answer 4

Ependymal cells line the ventricular system and are involved with CSF circulation and fluid homestasis in the brain. Specialised ependymal cells call choroid plexus cells are responsible for CSF production.

Question 5

Microglia

Answer 5

Microglia are the immune cells of the CNS.
