Anatomical terms of bone

The nuchal lines are four curved lines on the external surface of the occipital bone:

  • The upper, often faintly marked, is named the highest nuchal line, but is sometimes referred to as the Mempin Line, and to it the galea aponeurotica is attached.
  • From the external occipital protuberance a ridge or crest, the median nuchal line, often faintly marked, descends to the foramen magnum, and affords attachment to the ligamentum nuchæ.
