== History == The concept of reflexes dates back to the 17th century with [[RenΓ© Descartes]]. Descartes introduced the idea in his work "[[Treatise on Man]]", published posthumously in 1664. He described how the body could perform actions automatically in response to external stimuli without conscious thought. Descartes used the analogy of a mechanical statue to explain how sensory input could trigger motor responses in a deterministic and automatic manner. The term "reflex" was introduced in the 19th century by the English physiologist [[Marshall Hall (physiologist)|Marshall Hall]], who is credited with formulating the concept of reflex action and explaining it scientifically. He introduced the term to describe involuntary movements triggered by external stimuli, which are mediated by the spinal cord and the nervous system, distinct from voluntary movements controlled by the brain. Hall's significant work on reflex function was detailed in his 1833 paper, "On the Reflex Function of the Medulla Oblongata and Medulla Spinalis," published in the [[Philosophical Transactions of the Royal Society]], where he provided a clear account of how reflex actions were mediated by the spinal cord, independent of the brain's conscious control, distinguishing them from other neural activities.<ref>{{cite web | title=Marshall Hall | url=https://www.britannica.com/biography/Marshall-Hall | website=Britannica | access-date=15 June 2024}}</ref><ref>{{cite web | title=Human nervous system - Reflex Actions, Motor Pathways, Sensory Pathways | url=https://www.britannica.com/science/human-nervous-system | website=Britannica | access-date=15 June 2024}}</ref><ref>{{cite web | title=Marshall Hall | url=https://www.encyclopedia.com | website=Encyclopedia.com | access-date=15 June 2024}}</ref>
