Jugular tubercle

The Jugular tubercle is an oval bump found on the occipital bone, where the bone’s lateral and basilar sections come together. It is located just above the hypoglossal canal, which is itself above the occipital condyle. Found just in front and below the jugular foramen, it may sometimes feature an oblique groove on its posterior aspect. This groove acts as a pathway for the glossopharyngeal, vagus, and accessory nerves as they leave the medulla oblongata and move towards the jugular foramen. Understanding the anatomy of the jugular tubercle is crucial for safely performing neurosurgery near the jugular foramen, especially when removing tumors or vascular lesions in this area.
