FOR MED SCHOOL PROJECT - The University of Minnesota Class of 2004. Following the first year med students through their first year of medical school. IN THIS PHOTO: Students Robyn Engberg, right, and Norma Walks, left, (need to check spelling) react to the smell of the anatomy lab during a practice exam in their Gross Anatomy class. The fixatives used to preserve the cadavers often cause the lab to have a strong smell, and it takes time to adjust. Students begin their medical school education by dissecting a cadver , starting their dissection on the first day of school, beginning with the pectoral region.(Photo By JUDY GRIESEDIECK/Star Tribune via Getty Images)
