2. Myelination & Speed

• Oligodendrocytes (CNS): One cell wraps many axons.
• Schwann Cells (PNS): One cell wraps one axon.
• Saltatory Conduction: Impulse jumps between Nodes of Ranvier.

  6. Upper vs. Lower Motor Neuron (UMN vs. LMN) – Must Know!

  • LMN Lesion (Poliomyelitis, ALS): Flaccid paralysis, Areflexia, Muscle atrophy, Fasciculations.
  • UMN Lesion (Stroke, MS): Spastic paralysis, Hyperreflexia, Babinski sign (extensor plantar), Clonus. No atrophy.
  • Example: Draw the Corticospinal tract from motor cortex (Precentral gyrus) down to the Anterior Horn cell.
  • Check: Did you remember the decussation at the Medulla (Pyramids)?
