Reflex Arcs and Their Importance 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 brain, allowing quick reactions to danger. Using the example of touching a hot pan, the video details the flow of a reflex arc, involving receptor cells, sensory neurons, the spinal cord, relay neurons, motor neurons, and effectors. The video concludes by discussing various reflex actions, such as eye blinking, and emphasizes the protective role of reflex arcs in the nervous system.

How do reflex arcs protect the body from danger?

Describe the pathway of the impulse from the sensory neuron to the effector.
