  • Nerve cells ---> conducting units of the system

  • Glia and Neuroglia ---> Connecting and supporting cells

  • Schwann cells

  • Ependymal cells

  • Microglia

  • Oligodendrocytes

  • most abundant cells in the brain

  • responsable for communication between synapses

  • involved in the uptake and release of chemicals.

  • create myelin sheath around nerves

    • insulate nerves for faster conduction

    • repair damaged axons

  • create myelin (fatty material that wraps around a portion of the nerve cell)

  • play an important role in certain neurological diseases

  • Glial cells are located amongst nerve cells

  • Smaller than nerve cells

Occurs when a chemical is released and breaks down axons, also affecting glial cells. The function of some glial cells is to protect the axons. In alzheimers patients, the glial cells are not there to protect the axon.

  • chronic disease that affects the CNS

  • the immune system attacks the myelin sheath ---> causing inflammation and scar tissue

  • the scar tissue mainly affects the brain stem and spinal cord leading to decreased motor abilities over time
