Osteology
Roentgenogram of head and neck, left lateral view
The head was turned to the right in this view of the living female subject so that 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 oral cavity are outlined by their content of air, which produces a dark shadow in the view. Soft tissues are only faintly visible.
