Questions and Answers

What is the primary cause of the neurological disorder Guillain-Barré Syndrome?

  • A bacterial infection that releases toxins damaging Schwann cells and myelin sheaths
  • An autoimmune response targeting myelin sheaths in the peripheral nervous system (correct)
  • A viral infection that triggers an inflammatory response in the brain and spinal cord
  • A genetic mutation affecting the production of myelin proteins in the central nervous system
  • What is the primary function of the resting potential across a neuron's plasma membrane?

  • To establish a concentration gradient for the active transport of nutrients into the neuron
  • To facilitate the diffusion of ions across the membrane for neurotransmitter release
  • To maintain a state of readiness for the generation and propagation of action potentials (correct)
  • To prevent the formation of synaptic connections between neurons and their targets
  • Which of the following statements accurately describes the distribution of ions across the plasma membrane at resting potential?

  • The extracellular space has a higher concentration of potassium ions than the intracellular space
  • The concentrations of sodium and potassium ions are equal on both sides of the plasma membrane
  • The extracellular space has a higher concentration of sodium ions and a lower concentration of potassium ions compared to the intracellular space (correct)
  • The intracellular space has a higher concentration of sodium ions than the extracellular space
