Pterion

A junction of four bones on the lateral skull. Lies above the zygomatic arch. Often has an H-shaped sutural arrangement.

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.

A junction of four bones on the lateral skull.

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. A junction of four bones on the lateral skull
  2. Lies above the zygomatic arch
  3. Often has an H-shaped sutural arrangement
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 (2)

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

  • Sphenoid greater wing
  • Squamous temporal
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 pterion and justify your identification.
SUGGESTED ANSWER

A junction of four bones on the lateral skull. Lies above the zygomatic arch. Often has an H-shaped sutural arrangement.

02Why is a fracture here clinically important?
SUGGESTED ANSWER

The anterior division of the middle meningeal artery is closely related to its internal surface; injury can cause an extradural haematoma.

03Which four bones meet here?
SUGGESTED ANSWER

Frontal, parietal, squamous temporal and greater wing of sphenoid.
