Reflex Arc Reflex actions are automatic involuntary actions They are often there to keep us from harming ourselves For example if we were to touch something very hot with our hand, a reflex action would swiftly move it away from the source of danger The diagram below is a representation of what is known as a reflex arc The pain receptors in the finger sense the pain and stimulate GCSE Biology 5BI1H/01 Mark Scheme – November 12 Question Number Answer Acceptable answers Mark 1(a)(i) A – adaptations (1) Question Number Answer Acceptable answers Mark 1(a)(ii) Any one from the following • large surface area to facilitate heat loss (1) • insulating/fat layer (1) • correct adaptation of skin / fur / hair(1) (thick layer) of bacteria credit observable valid GCSE Biology students often find the reflex arc a difficult topic in the section on human coordination and response This is because it is the only type of response they learn about and doesn't really fit into a sensible flow of ideas on the various types of behaviours organisms can show But it is not too complicated, at least if you restrict yourself to ideas that might be tested in
