Match the function with the cell type.
Microglia
Astrocytes
Ependymal cells Satellite cells
Immune cells of the CNS
Make up the myelin and produce the neurilemma
Make up the blood brain barrier.
Supportive cells in PS
Monitor and produce the CSI
Make up the myelin in the CNS
Myelination of the axon: Myelin Sheath
* Insulating layer around the axon in the CNS and PNS that allow
for increased speed of conduction.
Production of myelin is termed myelination
CNS-oligodendrocytes
Composition of myelin:
. Consists of the plasma membrane
20% protein and 80% lipid
(phospholipids, cholesterol and
glycolipids)

Myelination of the axon: Schwann Cell (PNS)
• Cell repeatedly wraps its membrane around the
nerve fiber (axon) over 100 times.
• The outermost layer =neurilemma.
• Neurilemma contains the nucleus and cytoplasm.
Schwann Cell
Myelination of the axon: Schwann Cell (PNS)
