External jugular vein
The external jugular vein (Latin: vena jugularis externa) is a superficial vein of the neck that is formed by the union of the retromandibular vein and the posterior auricular vein.
The external jugular vein originates from the angle of the mandible, descends to the clavicle and the root of the neck, penetrating the deep cervical fascia and draining into the subclavian vein.
The main tributaries of the external jugular vein are:
- anterior jugular vein,
- posterior external jugular vein,
- transverse cervical vein, and
- suprascapular vein.
The external jugular vein collects blood from the scalp, face, neck, and the superficial muscles of the back.
