Dendrites | SHORT, highly Branched extensions of the cell body | carry impulses TOWARD the cell body |
Axon | LONG, slender extension of the cell body | carry impulses AWAY from the cell body - insulated by Neuroglia |
Terminal Filament | Synapse or Neuromuscular Junction | |
Synapse | Terminal Filament when joined to a DENDRITE of another Neuron | |
Neuromuscular Junction | Terminal Filament when joined at a Muscle Cell | |
Amitotic | the direct method of cell division | |
Neuroglia | Supportive cells among/around neurons | |
Schwann Cells | wrapped around Peripheral | provide support and axon insulation; improve SPEED of nerve impulse conduction |
Nodes (of Ranvier) | GAPS between Schwann cells | serve as relay points for nerve impulses |
Oligodendrocytes | wrapped around central neurons | provide MYELINATION similar to Schwann cells |
Astrocytes | crowded among central neurons | Support and Link neurons to blood CAPILARIES - regulate DIFUSSION; contribute to BLOOD-BRAIN Barrier |
