The head is turned to the right in this view of a living female subject and as a result the cervical vertebrae lie in various degrees of rotation. The lower vertebrae are more nearly in the anteroposterior position than the upper ones. The respiratory passages and the oral cavity are outlined by their content of air, which produces a dark shadow in the view. Soft tissues are only faintly visible. This film was obtained through the courtesy of Dr. Charles E. Duisenberg.
