BIO CELLS
Line ventricles (brain) and central canal and (spinal cord) assist in producing, circulating and monitoring cerebrospinal fluid.
Ependymal
Maintain blood-brain barrier provide structurres support; regulate ion, nutrient and dissolved gas concentrations absorb and recycle neurotransmitters, form scar tissue after injury
Astrocytes
Myelinate CNS axons and provide structural framework
Obligodendrocytes
Remove Cell Debris, wastes, and pathogens by phagocytosis
Microglia
Surround neuron cell bodies in ganglia; regulate O2, CO2, nutrient and neurotransmitter levels around neurons in ganglia
Satellite Cells
Surround all neurons in PNS, responsible for myelination of peripheral axons participate in repair process after injury
Schwann cells
