Understanding Reflex Arcs in the Nervous System

This video tutorial explains reflex arcs, which are neuron pathways enabling reflex actions. Reflex actions are automatic responses to stimuli that bypass the conscious brain, protecting the body from harm. The video details the reflex arc process, involving pain receptors, sensory neurons, relay neurons, and motor neurons, using the example of touching a hot pan. It also highlights other reflex examples, emphasizing the general pathway from receptors to effectors.
