Welcome to Wikipedia. We welcome and appreciate your contributions, including your edits to Reflex arc, but we cannot accept original research. Original research refers to material—such as facts, allegations, and ideas—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. Thank you. McGeddon (talk) 15:00, 13 February 2015 (UTC)
