Obliquus Capitis Superior - Podcast Version 0:00 / 0:00 1x 0.25x 0.5x 0.75x 1x 1.25x 1.5x 1.75x 2x The obliquus capitis superior is a suboccipital muscle of the neck. It is located laterally within the suboccipital compartment. Attachments: Originates from the transverse process of C1 and attaches onto the occipital bone (between the superior and inferior nuchal lines). Actions: Extension of the head. Innervation: Suboccipital nerve (posterior ramus of C1) Blood supply: Vertebral artery and the deep descending branch of the occipital artery.

Learn More Frequent questions What is the obliquus capitis superior? The obliquus capitis superior is a suboccipital muscle located in the neck, specifically within the lateral suboccipital compartment. It plays a key role in the extension of the head. Where does the obliquus capitis superior originate and attach? This muscle originates from the transverse process of the first cervical vertebra (C1) and attaches to the occipital bone, situated between the superior and inferior nuchal lines. What is the primary action of the obliquus capitis superior? The primary action of the obliquus capitis superior is to extend the head. This movement is essential for various head and neck functions. Which nerve innervates the obliquus capitis superior? The obliquus capitis superior is innervated by the suboccipital nerve, which is the posterior ramus of the first cervical nerve (C1). This nerve supplies the muscle, allowing it to function properly. What are the blood supply sources for the obliquus capitis superior? The obliquus capitis superior receives its blood supply from the vertebral artery and the deep descending branch of the occipital artery. These vessels ensure adequate perfusion for the muscle's activity. Rate This Article
