Abstract

“Rollie Hendrix,” a 35-year-old husband and father of three children, has been experiencing headaches and palpitations of increasing frequency and severity over the past six months. In addition, he has had periods of intense anxiety and panic attacks. Students read about these symptoms and then answer a set of directed questions designed to teach facts and principles of anatomy and physiology using reference books, textbooks, the Internet, and each other as sources of information. The case has been used in both a sophomore-level course in human anatomy and physiology and a senior-level course in general physiology.
