The jugular foramen is a large, irregularly shaped opening between the temporal and occipital bones. Specifically, it is formed between the jugular fossa of the petrous part of the temporal bone and the jugular process of the occipital bone. It is found lateral to the foramen magnum and posterior to the carotid canal.
It contains a notch, the intrajugular process, which divides the foramen into a larger posterolateral compartment and a smaller anteromedial compartment. It transmits the inferior petrosal sinus, internal jugular vein and three cranial nerves: glossopharyngeal (CNIX), vagus (CNX) and the descending part of the spinal accessory (CNXI) nerve.
