Exercise
Peripheral Nervous System and Reflex Arc
In this engaging exercise, students will explore the intricacies of the peripheral nervous system and the reflex arc, discovering how sensory information is processed and actions are triggered in real-time, while also creating models to demonstrate these vital physiological pathways. Through hands-on activities and collaborative discussions, learners will gain a deeper understanding of the body's rapid response mechanisms and their importance in maintaining health and safety.
