Lesser wing of sphenoid

Thin wing extending laterally from sphenoid body. Posterior edge helps mark anterior/middle cranial-fossa boundary. Optic canal lies near its root.

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.

Thin wing extending laterally from sphenoid body.

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. Thin wing extending laterally from sphenoid body
  2. Posterior edge helps mark anterior/middle cranial-fossa boundary
  3. Optic canal lies near its root
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 lesser wing of sphenoid and justify your identification.
SUGGESTED ANSWER

Thin wing extending laterally from sphenoid body. Posterior edge helps mark anterior/middle cranial-fossa boundary. Optic canal lies near its root.

02Which part of the orbit does it help form?
SUGGESTED ANSWER

The posterior roof of the orbit.

03What is the anterior clinoid process?
SUGGESTED ANSWER

A medial projection at the posterior end of the lesser wing, related to dural attachments and the optic canal region.
