1
New cards

Astrocytes

  • Found in the CNS.

  • Provide structural support for neurons and help maintain the blood-brain barrier.

  • Regulate nutrient and ion balance around neurons.

2
New cards

Oligodendrocytes

  • Found in CNS

  • Form myelin sheath around axons in CNS —> speed up signal transmission

3
New cards

Microglia

  • Act as immune cells of CNS

  • Engulf and digest cellular debris, pathogens, and damage neurons

4
New cards

Ependymal Cells

  • Found in CNS

  • Line the ventricles of the brain and the central canal of the spinal cord

  • Produce and circulate cerebrospinal fluid (CSF)

5
New cards

Schwann cells

  • Found in PNS

  • Form the myelin sheath around axon in the PNS, aiding faster signal conduction

6
New cards

Satellite Cells

  • Found in PNS

  • Surround neuron cell bodies in ganglia and help regulate the environment around neurons, especially nutrients and waste.
