STRUCTURE & FUNCTION

Understand what you see.

Oval opening in the greater wing of sphenoid.

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. Oval opening in the greater wing of sphenoid
  2. Lies posterolateral to foramen rotundum
  3. Opens toward infratemporal fossa
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.

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 ovale and justify your identification.
SUGGESTED ANSWER

Oval opening in the greater wing of sphenoid. Lies posterolateral to foramen rotundum. Opens toward infratemporal fossa.

02What is the principal nerve transmitted?
SUGGESTED ANSWER

Mandibular division of trigeminal nerve (V3); additional vessels and a variably coursing lesser petrosal nerve may be present.

03Which trigeminal division is mixed sensory and motor?
SUGGESTED ANSWER

V3; its motor fibres supply muscles including those of mastication.
