The rectus capitis lateralis muscle ( Latin for "lateral straight head muscle") is a small, short and flat skeletal muscle in the area of the deep neck and lies on the side of the first head joint . It runs from the transverse process of the atlas to the jugular process of the occiput .
It belongs to the deep neck triangle , but not to the so-called local back muscles in the narrower sense, because it is innervated by the ramus anterior of the C1, just like the rectus capitis anterior muscle . The short neck muscles also include the rectus capitis posterior major , the rectus capitis posterior minor , the obliquus capitis superior and the obliquus capitis inferior muscles . This muscle group is innervated by the first spinal nerve of the neck (C1), the suboccipital nerve, and causes the head to be held upright.
