These run forward along the costal cartilages with the internal mammary artery between the two of each lateral pair. The common trunk formed by the union is very short. Each innominate divides into three trunks, the vertebral, common jugular, and subclavian. The vertebral goes to the head through the vertebral canal. The common jugular is very short and is formed by the union of an external and internal jugular. The external lies laterally along the neck. It is formed at th

Each innominate divides into three trunks, the vertebral, common jugular, and subclavian. The vertebral goes to the head through the vertebral canal. The common jugular is very short and is formed by the union of an external and internal jugular. The external lies laterally along the neck. It is formed at the base of the skull by the union of veins from the exterior of the head and lower jaw. A short distance back of its anterior end it is joined by a vein running forward from the dorsal aspect of the shoulder and neck. About half way down two smaller ones unite with it that come from the dorsal surface of the neck. Fear its lower end, finally, a large branch curves over the anterior aspect of the shoulder from the dorsal surface of the same and unites with it just in front of the shoulder. The mus- cles of the neck and shoulder are hence abun- dantly supplied with both arteries and veins; the veins of this region emptying into the external jugular corresponding in size and numbers with the branches of the thyroid axis. The internal jugular is formed at the base of the skull by the union of namerous branches from the exterior and interior of the head. The most important of these are: Two veins curving around the pos- terior ends of,the lower jaw from the muscles laterad of this and from the posterior lateral aspect of the head; a vein from the interior of the cranium which leaves the same by a small foramen in the anterior part of the ear capsule and which then goes backward and downward along the lesser cornu of the liyoid and receives a branch from the tongue; a vein from the base of the head and the soft palate, and the main trunk from the jugular foramen in the skull.
