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.
The jugular fossa is located in the temporal bone, posterior to the carotid canal and the cochlear aqueduct.. In the bony ridge dividing the carotid canal from the jugular fossa is the small inferior tympanic canaliculus for the passage of the tympanic branch of the glossopharyngeal nerve.

Greater sciatic foramen, a major foramen of the pelvis; Interventricular foramen, channels connecting ventricles in the brain; Intervertebral foramen, foramina formed between vertebrae; Lesser sciatic foramen, an opening between the pelvis and the posterior thigh; Obturator foramen, the opening created by the ischium and pubis bones of the pelvis
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.
There are also a “huge number” of interactions likely occurring between the brain and the ovaries throughout a woman’s life, Garrison says, but “we don’t know all the words in that ...
