neurons and glia

• what are the four shapes of neurons?

  multipolar, bipolar, unipolar, and anaxionic
• what are the 4 types of neurons in the cns?

  astrocytes, microglia, ependymal cells, snd ogliodendrocytes
• which glia has these functions: supply nutrients to neurons, ensheath blood capillaries, and response to injury?

  Astrocytes
• which glia has these 2 functions: immune cells of the CNS, and engulfs microorganisms and debris?

  Microglia
• which glia has these 2 features: line fluid filled spaces of the brain and spinal cord, have cilia to circulate CSF?

  ependymal cells
• which glia has these 2 features: support nerve fibres, and ensheath them with myelin?


  ogliodendrocytes
• what glia is in the PNS?

  Peripheral nervous system glia
• what are the functions of a peripheral nervous system glia ?


  support peripheral nerve fibers and ensheath them with myelin
• what are the gaps between myelin sheaths called and what is there function?

  Nodes of ranvier, increases conduction velocity
• what is the junction between neurons called?

  synapse
