What is a Reflex Arc

The video explains reflex reactions, which are immediate, unconscious responses to stimuli that protect us. It covers the reflex arc, a pathway that allows quick responses by bypassing the brain and acting through the spinal cord. The video distinguishes between simple reflexes, which are innate, and conditioned reflexes, which involve learning, using Pavlov's dogs as an example. Although the brain is bypassed initially, it receives the message to decide on further actions. Reflex reactions are crucial for survival, providing rapid responses to potential dangers.
