Obliquus capitis superior (left) (Musculus obliquus capitis superior)

Layer: Muscles

Educational content only — not medical advice.

Anatomy

One of the four suboccipital muscles fine-tuning the atlanto-occipital joint for visual balance, from the atlas transverse process to the occipital bone.

Origin & insertion

Transverse process of the atlas.

Action

Fine side-bending of the head toward its side and steadies the atlanto-occipital joint during reading and gaze.

Innervation

Posterior ramus of C1 (suboccipital nerve).

Clinical notes

Its fatigue with the other suboccipitals tilts the head at screens and worsens visual strain; the suboccipital triangle it bounds is the neurosurgical corridor to the vertebral artery.
