Neuronal communication

• Myelination

  • Insulated axon
  • Less action potentials need to be triggered across the same axon length
  • Increases speed of conductance
• Axon diameter

  • Thicker axon/large axon diameter
  • Increased surface area for diffusion
  • Reduced electrical resistance
  • Increases speed of conductance
• Cold temperatures

  • Less kinetic energy for ions
  • Decreases speed of conductance
• The movement of charge is called a nerve impulse
