Elaine N. Marieb began her teaching career at Springfield College, where she taught anatomy and physiology to physical education majors. She then joined the faculty of the Biological Science Division of Holyoke Community College after receiving her Ph.D. in zoology from the University of Massachusetts at Amherst. While teaching at Holyoke Community College, Dr. Marieb pursued her nursing education, which culminated in a Master of Science degree with a clinical specialization in gerontology from the University of Massachusetts. Dr. Marieb has given generously to provide opportunities for students to further their education. She contributes to the New Directions, New Careers Program at Holyoke Community College by providing several full-tuition scholarships each year for women returning to college after a hiatus or who are attending college for the first time and would otherwise be unable to continue with their studies without financial support. She funds the E. N. Marieb Science Research Awards at Mount Holyoke College, which promotes research by undergraduate science majors, and generously contributed to the University of Massachusetts at Amherst where she provided funding for reconstruction and instrumentation of a cutting-edge cytology research laboratory that bears her name. In 1994, Dr. Marieb received the Benefactor Award from the National Council for Resource Development, American Association of Community Colleges, which recognizes her ongoing sponsorship of student scholarships, faculty teaching awards, and other academic contributions to Holyoke Community College. In May 2000, the science building at Holyoke Community College was named in her honor. Additionally, while actively engaged as an author, Dr. Marieb serves as a consultant for the Benjamin Cummings Interactive Physiology¨ CD-ROM series, and is an active member of the Human Anatomy and Physiology Society (HAPS), the American Association for the Advancement of Science (AAAS), and Sigma Xi. Anatomy & Physiology, Second Edition is the latest expression of her commitment to student needs in their pursuit of the study of A&P.

Dr. Katja Hoehn is an instructor in the Department of Chemical and Biological Sciences at Mount Royal College in Calgary, Canada. Dr. Hoehn's first love is teaching. Her teaching excellence has been recognized by several awards during her 14 years at Mount Royal College. These include a PanCanadian Educational Technology Faculty Award (1999), a Teaching Excellence Award from the Student’s Association of Mount Royal College (2001), and the Mount Royal College Distinguished Faculty Teaching Award (2004). Dr. Hoehn received her M.D. (with Distinction) from the University of Saskatchewan, and her Ph.D. in Pharmacology from Dalhousie University. In 1991, the Dalhousie Medical Research Foundation presented her with the Max Forman (Jr.) Prize for excellence in medical research. During her Ph.D. and postdoctoral studies, she also pursued her passion for teaching by presenting guest lectures to first- and second-year medical students at Dalhousie University and at the University of Calgary. Dr. Hoehn has been a contributor to several books and has written numerous research papers in Neuroscience and Pharmacology. She oversaw the recent revision of the Interactive Physiology modules, and co-authored the newest module, The Immune System. Dr. Hoehn is also actively involved in the Human Anatomy and Physiology Society (HAPS).
