Frontal bone

Forms the forehead and roof of the orbit. Contains frontal air sinuses in the adult. Meets the parietal bones at the coronal suture.

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.

Forms the forehead and roof of the orbit.

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. Forms the forehead and roof of the orbit
  2. Contains frontal air sinuses in the adult
  3. Meets the parietal bones at the coronal suture
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.

  • Frontal squama
  • Orbital plates
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 frontal bone and justify your identification.
SUGGESTED ANSWER

Forms the forehead and roof of the orbit. Contains frontal air sinuses in the adult. Meets the parietal bones at the coronal suture.

02What forms the roof of the orbit?
SUGGESTED ANSWER

Mainly the orbital plate of the frontal bone, with a posterior contribution from the lesser wing of the sphenoid.

03Where do the frontal sinuses drain?
SUGGESTED ANSWER

Into the middle nasal meatus through the frontal drainage pathway; the exact pathway varies.
