longus capitis การใช้

• It includes the prevertebral muscles ( longus colli and longus capitis ), vertebral artery, vertebral vein, scalene muscles, phrenic nerve and part of the brachial plexus.
• On either side of the middle line the longus capitis and rectus capitis anterior are inserted, and immediately in front of the foramen magnum the anterior atlantooccipital membrane is attached.
• Behind, the artery is separated from the transverse processes of the cervical vertebrae by the longus colli and longus capitis muscles, the sympathetic trunk being interposed between it and the muscles.
• The "'ascending cervical artery "'is a small branch which arises from the inferior thyroid artery as it passes behind the carotid sheath; it runs up on the anterior tubercles of the transverse processes of the cervical vertebrae in the interval between the anterior scalene muscle and the longus capitis.
• It is in relation, behind, with the longus capitis, the superior cervical ganglion of the sympathetic trunk, and the superior laryngeal nerve; laterally, with the internal jugular vein and vagus nerve, the nerve lying on a plane posterior to the artery; medially, with the pharynx, superior laryngeal nerve, and ascending pharyngeal artery.
