Anatomical terminology

It divides into two branches:

• an anterior, which passes forward and joins anterior facial vein, to form the common facial vein, which then drains into the internal jugular vein.
• a posterior, which is joined by the posterior auricular vein and becomes the external jugular vein.

Parrot's sign is a sensation of pain when pressure is applied to the retromandibular region.
