The musculus obliquus capitis inferior ( Latin for "lower oblique head muscle", in animals called "rear oblique head muscle" - musculus obliquus capitis caudalis -) is a skeletal muscle in the neck area and lies on the back of the second head joint . It runs from the spinous process of the axis to the atlas wing ( massa lateralis ).
It is one of the five short neck muscles belonging to the so-called local back muscles , which also include the posterior rectus capitis major , posterior rectus capitis minor , superior oblique capitis muscle and lateral rectus capitis muscle . The inferior obliquus capitis muscle (OCI) is the only one of these short neck muscles that does not attach to the occiput itself. This muscle group is innervated by the first spinal nerve of the neck (C1) and causes the head to be held up.
