Jugular foramen

Irregular opening between petrous temporal and occipital bones. Lateral to foramen magnum. Related to the sigmoid sinus and upper internal jugular vein.

Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.

STRUCTURE & FUNCTION

Understand what you see.

Irregular opening between petrous temporal and occipital bones.

Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.

01 / IDENTIFICATION

How to recognise it.

  1. Irregular opening between petrous temporal and occipital bones
  2. Lateral to foramen magnum
  3. Related to the sigmoid sinus and upper internal jugular vein
02 / KEY STRUCTURES

Point them out.

Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.

Related features & study points (3)

Additional relations, attachments or microscopic details to revise alongside this plate. These are separate from its numbered image landmarks.

03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

Examiner-style prompts: identify the structure, explain its relations, then answer the applied follow-up. These are revision questions, not authenticated past papers.

01Identify jugular foramen and justify your identification.
SUGGESTED ANSWER

Irregular opening between petrous temporal and occipital bones. Lateral to foramen magnum. Related to the sigmoid sinus and upper internal jugular vein.

02Which cranial nerves pass through it?
SUGGESTED ANSWER

Glossopharyngeal IX, vagus X and accessory XI; venous structures also traverse the foramen.

03Which major vein begins at this region?
SUGGESTED ANSWER

The internal jugular vein is continuous with the sigmoid sinus at the jugular foramen.
