Round opening in the sphenoid greater-wing region. Connects middle cranial fossa to pterygopalatine fossa. Anterior to foramen ovale.

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.

Round opening in the sphenoid greater-wing region.

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. Round opening in the sphenoid greater-wing region
  2. Connects middle cranial fossa to pterygopalatine fossa
  3. Anterior to foramen ovale
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 foramen rotundum and justify your identification.
SUGGESTED ANSWER

Round opening in the sphenoid greater-wing region. Connects middle cranial fossa to pterygopalatine fossa. Anterior to foramen ovale.

02What is its main content?
SUGGESTED ANSWER

Maxillary division of the trigeminal nerve (V2).

03How is it distinguished from foramen ovale?
SUGGESTED ANSWER

Rotundum is smaller and more anterior; ovale transmits V3 into the infratemporal region.
