- Neurons
- Function: Motor neuron/Sensory neuron
- Components:
- Dendrites w/ Dendritic spines that increase surface area
- Cell body (=Soma)
- Axon
- Axion Hillock
- Myelin Sheath (말린 부분) made of Schwann cells + Nodes of Ranvier (the inbetween nodes)
- Presynaptic terminal
- Increases the speed of impulse transmission: Saltatory conduction
- Systemic: efferent /afferent neuron
- Glia
- Microglia: immune system
- Oligodendrocytes (@central nervous system), Schwann Cells (@Periphery) build & maintain myelin sheath
- Radial glia: guide development & movement during embryo
