Origin: Lateral mass of atlas
Insertion: Lateral half of the inferior nuchal line
Nerve: Suboccipital nerve
The Obliquus capitis superior (Obliquus superior), narrow below, wide and expanded above, arises by tendinous fibers from the upper surface of the transverse process of the atlas, joining with the insertion of the preceding. It passes upward and medialward, and isinserted into the occipital bone, between the superior and inferior nuchal lines, lateral to the Semispinalis capitis.
