Nasal septum

Midline partition separating nasal cavities. Bony components include ethmoid perpendicular plate and vomer. Anterior portion includes septal cartilage.

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.

Midline partition separating nasal cavities.

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. Midline partition separating nasal cavities
  2. Bony components include ethmoid perpendicular plate and vomer
  3. Anterior portion includes septal cartilage
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 nasal septum and justify your identification.
SUGGESTED ANSWER

Midline partition separating nasal cavities. Bony components include ethmoid perpendicular plate and vomer. Anterior portion includes septal cartilage.

02Is the septum entirely bony?
SUGGESTED ANSWER

No. Its anterior portion includes septal cartilage.

03Where is Little's area?
SUGGESTED ANSWER

On the anterior nasal septum; it contains an arterial anastomotic area and is a frequent source of anterior epistaxis.
