1. Microglial Cell
Sacs containing enzymes that bark down wastes
Defensive function to remove foreign tissue and dead cells by attacking it
Forms myelin around axons in the PNS
Secretes cerebrospinal fluid (CSF) and fills the ventricles.
2. Oligodendroglial Cell
Sacs containing enzymes that bark down wastes
Aids nervous system repair
Mylelinate axons in the brain and spinal cord in the CNS
Carries positive and negative charges across the cell membrane
3. Ependymal Cell
Aids nervous system repair
Secretes cerebrospinal fluid (CSF) and fills the ventricles.
Defensive function to remove foreign tissue and dead cells by attacking it
Carries impulses from dendrites to the rest of the body
4. Schwann Cell
Forms myelin around axons in the PNS
Sends efferent signals out to the spinal cord to control virtually all of the body’s movements
Mylelinate axons in the brain and spinal cord in the CNS
Helps form blood-brain barrier and heals scarring
5. Astrocyte
Fluid in which the cell's internal structures are suspended
Promotes sleep and activates the parasympathetic rest-and-digest system
Helps form blood-brain barrier and heals scarring
Carries impulses from dendrites to the rest of the body
