Quizplus · Accepted Answer

The nuchal plane, which is a flat surface on the occipital bone, and the foramen magnum, which is the opening in the base of the skull through which the spinal cord passes, are two skeletal features that reveal the orientation of the skull to the vertebral column. When the skull is oriented properly, the nuchal plane should be parallel to the ground and the foramen magnum should be aligned with the first cervical vertebra.
