Neuron and Action Potential

• Neurons
  • Types of nervous system cells
    • Neurons
    • Glial cells
  • Structure of the neuron
    • Cell body (soma)
    • Dendrite
    • Axon
  • Electrical signals and potentials
  • Propagation of nerve impulses
  • Neurotransmitters

Objectives

• Describe the functions of glial cells
• Identify parts of the neuron on drawings or from descriptions
• Briefly explain how the action potential is generated and propagated along the length of the axon
• Briefly explain how electrical signals are transmitted across synapses using neurotransmitters
