Questions and Answers

What is the relationship between the myelin sheath and the organization of nervous tissue?

  • The myelin sheath acts as an insulating layer around nerve fibers, allowing for faster transmission of electrical signals (correct)
  • The myelin sheath is responsible for transmitting electrical signals within the nervous tissue
  • The myelin sheath provides structural support to the nervous tissue
  • The myelin sheath regulates the flow of neurotransmitters within the nervous tissue

    • Which of the following is NOT a major function of the nervous system?

  • Receiving sensory inputs
  • Integrating information
  • Maintaining homeostasis (correct)
  • Controlling muscles and glands

    • Which of the following best describes the resting membrane potential?

  • The electrical signal that occurs when a neuron is at rest and not transmitting any information (correct)
  • The point at which a neuron reaches its maximum firing rate
  • The electrical signal that occurs when a neuron is actively transmitting information
  • The point at which a neuron becomes completely depolarized
