  Veins (Anatomy) - LoveToKnow 1911
The frontal vein on the forehead passes down on the inner side of the eyelids, where it is known as the angular, and then becomes the facial vein, which runs down to an inch in front of the angle of the jaw, whence it passes into the neck to join the common facial.
The chief tributaries of the innominate veins are the vertebral, the internal mammary and the inferior thyroid.
In the Dipnoi (mud-fish) a pulmonary vein from the lung-like swim-bladder is formed and an inferior vena cava or postcaval vein carries the blood from the kidneys to the heart.

It commences in the substance of the parotid gland, on a level with the angle of the mandible, and runs perpendicularly down the neck, in the direction of a line drawn from the angle of the mandible to the middle of the clavicle at the posterior border of the Sternocleidomastoideus.
At the root of the neck the right internal jugular vein is placed at a little distance from the common carotid artery, and crosses the first part of the subclavian artery, while the left internal jugular vein usually overlaps the common carotid artery.
The Anterior Vertebral Vein commences in a plexus around the transverse processes of the upper cervical vertebræ, descends in company with the ascending cervical artery between the Scalenus anterior and Longus capitis muscles, and opens into the terminal part of the vertebral vein.

 Chapter 40: Muscles, vessels, nerves and joints of the back
The vertebral artery is one of the main vessels to the brain.
The joints of the vertebral column are (1) those between the bodies of adjacent vertebrae (intervertebral discs), (2) those of the vertebral arches (between articular processes), (3) the atlanto-occipital and atlanto-axial joints, (4) the costovertebral joints, and (5) the sacro-iliac joint.
The vertebral arches are connected by ligaments, particularly strong in the lumbar region, e.g., the ligamenta flava between the laminae.

 Section 7 Chapter 4 Injuries to the Neck
Although the jugular vein is in the operative field and can be easily harvested, it is better not to interfere with venous outflow in a neck in which the arterial inflow is to undergo repair; in addition, the jugular vein is very thin and difficult to handle.
Although the vertebral artery is also accessible in the spaces between the transverse processes, there are a number of venous branches in these regions, and it is therefore safer to approach the artery within the confines of the bony foramina.
At the depth of the vertebral artery, the white, cordlike elements of the brachial plexus are often visible in the superolateral aspect of the wound.

Thrombosis of the jugular vein from a deep infection of the neck is probably not due to direct infection of the carotid sheath, but rather to the fact that infectious material follows tributaries of the internal jugular vein to reach the sheath.

 eMedicine - Vertebral Artery Atherothrombosis : Article Excerpt by: Mark Eskandari, MD
For hemodynamic symptoms to occur, significant disease must be present in both of the vertebrals, and compensatory contribution from the anterior circulation via the circle of Willis must be incomplete.
However, current estimates suggest that up to a third of vertebrobasilar ischemic episodes are caused by distal embolization from plaques or mural lesions of the subclavian, vertebral, and/or basilar arteries.
The most common disease affecting the vertebral artery is atherosclerosis.
