[edit] Contents
The jugular foramen may be subdivided into three compartments, each with their own contents.
- The anterior compartment transmits the inferior petrosal sinus.
- The intermediate transmits the glossopharyngeal, vagus, and accessory nerves.
- The posterior transmits the sigmoid sinus (becoming the internal jugular vein) and some meningeal branches from the occipital and ascending pharyngeal arteries.
[edit] Clinical significance
Obstruction can result in "Vernet's syndrome".[1][2]
