A jugular foramen is one of the two (left and right) large foramina (openings) in the base of the skull, located behind the carotid canal. It is formed by the temporal bone and the occipital bone . It allows many structures to pass, including the inferior petrosal sinus , three cranial nerves , the sigmoid sinus , and meningeal arteries.
In the jugular foramen, it receives one or two filaments from the cranial part of the nerve, or else joins it for a short distance and then separates from it again. As it exits from the jugular foramen, it runs backward in front of the internal jugular vein in 66.6% of cases, and behind it in 33% of cases.

Extending lateralward from the posterior half of the condyle is a quadrilateral plate of bone, the jugular process, excavated in front by the jugular notch, which, in the articulated skull, forms the posterior part of the jugular foramen. The jugular notch may be divided into two by a bony spicule, the intrajugular process, which projects ...
The jugular process is a quadrilateral or triangular bony plate projecting lateralward from the posterior half of the occipital condyle; it is a part of the lateral part of the occipital bone. [ 1 ] The jugular process is excavated in front by the jugular notch of occipital bone (which forms the posterior part of the jugular foramen ).
Superiorly, the carotid sheath encircles the margins of the carotid canal and jugular foramen. [2] Inferiorly, it terminates at the arch of the aorta; [2] it is continuous inferiorly with the axillary sheath at the venous angle. [3] Its inferior end occurs at the level of the first rib and sternum inferiorly (varying between the levels of C7 ...
A glomus jugulare tumor grows in the temporal bone of the skull, in an area called the jugular foramen. The jugular foramen is also where the jugular vein and several important nerves exit the skull. This area contains nerve fibers, called glomus bodies. Normally, these nerves respond to changes in body temperature or blood pressure.
