Q

what is a neuron and what is its structure ?

A
  • the main electrically exitable cell
  • it has dendrietes (where post synaptic input sites are)
  • it has an axon (conducts)
  • it has synaptic terminals (site for pre-synaptic output of neurotransmitter release)

Q

what are the 4 types of a Glia in the central nervous system?

A
  • Oligodendrocyte – wrap/insulate nerve processes.
  • Astrocyte – line the Blood-Brain-Barrier (BBB)
  • Ependymal – produce CerebroSpinal Fluid of ventricles
  • Microglia - phagocytose immune role.
