Obliquus capitis inferior

The obliquus capitis inferior muscle (/əˈblaɪkwəs ˈkæpɪtɪs/) is the larger of the two oblique muscles of the neck. It arises from the apex of the spinous process of the axis and passes laterally and slightly upward, to be inserted into the lower and back part of the transverse process of the atlas.Position of obliquus capitis inferior muscle (shown in red).Close up.

The obliquus capitis inferior muscle (/əˈblaɪkwəs ˈkæpɪtɪs/) is the larger of the two oblique muscles of the neck. It arises from the apex of the spinous process of the axis and passes laterally and slightly upward, to be inserted into the lower and back part of the transverse process of the atlas. It lies deep to the semispinalis capitis and trapezius muscles. The muscle is responsible for rotation of the head and first cervical vertebra (atlanto-axial joint). It forms the lower boundary of the suboccipital triangle of the neck.
