Main veins of the head and neck
After completing this study unit you will be able to:
1. Identify the main veins that drain the head and neck.
2. Learn the main tributaries of those veins and which areas they drain.
The head and neck are drained by three major paired venous vessels: internal jugular, brachiocephalic, and subclavian veins.
- Internal jugular vein drains the majority of the face, brain and neck, which is why it's considered to be the principal vein of the head and neck regions.
- Brachiocephalic veins arise from the confluence of the same sided internal jugular and subclavian veins. The left and right brachiocephalic veins merge to form the superior vena cava that conveys all the venous blood from the head and neck directly into the right atrium of the heart.
- Subclavian vein primarily drains the upper limb, but it also collects the blood from the smaller jugular and vertebral veins.
This video tutorial will provide you with an overview of the main veins of the head and neck.
