This guide explores the concept of action potentials and their role in nerve impulses. It covers neuron anatomy, emphasizing the myelin sheath's importance in saltatory propagation. Activities include reflections on relay games compared to neuron impulses and examining sensory systems in the context of how they activate neurons to transmit messages to the brain. Students will review key topics from their textbook, engage in collaborative study, and prepare presentations to deepen their understanding of neural communication.
