Jugular process
Processus jugularis
Definition
The jugular process is a four-sided bony plate stretching out from the rear part of the occipital condyle to the side, and it joins with the petrous part of the temporal bone. It is more visible from underneath the skull, or from the inferior view of the skull base. The front edge of this plate has a jugular notch, which forms the rear edge of the jugular foramen when the parts of the skull are fitted together.
On the top surface of the jugular process, there is a groove for the sigmoid sinus. This groove curves inward and forward, merging with the jugular notch and foramen. The bottom surface of the jugular process is rough and serves as an attachment point for the Rectus capitis lateralis muscle and the lateral atlantooccipital ligament.
