Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the main ion that causes depolarization during an action potential?

  • Potassium (K⁺)

  • Sodium (Na⁺)

πŸ’‘ Hint: Remember which ion enters the cell during depolarization.

Question 2

True or False: The refractory period allows for immediate subsequent action potentials.

  • True
  • False

πŸ’‘ Hint: Think about the need for recovery before the next signal.
