When the medical student first unzips the body bag in the anatomy lab, the cadaver's eyes are closed. When they body is displayed at the morgue, the eyes are open.
While performing the autopsy, Dr. Hunt does not wear a protective mask, yet the med students all wear one. These masks are worn to protect the mouth, nose, and eyes from contamination. She also does not tie her hair back, which could result in contamination of the evidence.
