A Tradesman’s Journey Back from a Cerebral Incident 

This directed case study tells the story of a middle-aged man with hypertension and hyperlipidemia who experiences an ischemic cerebrovascular accident. The case provides an opportunity for students to integrate the brain's functional anatomy related to control of speech and body movement, and to examine how disruption of the brain's blood supply can have systemic effects. Students learn the anatomy of the brain's blood supply and explore the neural integration of upper motor neurons in the quadriceps reflex. Group discussion is used to teach the post-stroke symptoms of hemiparesis (primarily in the lower extremity), dysphasia, and alien hand syndrome. The case was originally developed for upper-level undergraduate biology majors following their coursework in anatomy, physiology, and neuroscience. The case is also appropriate for any upper-level college undergraduate or graduate course that covers the cardiovascular system, structure and function of the brain's cerebrum, and the brain's blood supply (circle of Willis and the general supply of each cerebral artery).

Uretero What?: A Systems-Level View of a Pregnancy with Medical Complications

This case study follows a woman faced with a series of difficult medical decisions. Students apply systems-level physiology as they explore a pregnancy with medical complications and discuss situations involving life-changing decisions prompted by modern medical technologies. This case could be used in an advanced biology course at the high school level, or in undergraduate courses in general biology, human anatomy and physiology, human health, human sexuality, medical ethics, sociology, or women’s studies. The case study also would be applicable to first-year medical students in a course in medical physiology as well as students in nurse practitioner, midwifery, or physician’s assistant programs.
