Anatomical terms of bone
[edit on Wikidata]

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 epicranial aponeurosis.

  • Below the highest nuchal line is the superior nuchal line. To it is attached, the splenius capitis muscle, the trapezius muscle and the occipitalis.

  • 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 nuchal ligament.

  • Running from the middle of this line is the inferior nuchal line. Attached are the obliquus capitis superior muscle, rectus capitis posterior major muscle, and rectus capitis posterior minor muscle.
