Lacrimal bone

A small thin bone in the medial orbital wall. Related to the lacrimal sac fossa. Lies anterior to the orbital plate of ethmoid.

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 small thin bone in the medial orbital wall.

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 small thin bone in the medial orbital wall
  2. Related to the lacrimal sac fossa
  3. Lies anterior to the orbital plate of ethmoid
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 (3)

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

  • Lacrimal groove
  • Posterior lacrimal crest
  • Medial orbital wall
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 lacrimal bone and justify your identification.
SUGGESTED ANSWER

A small thin bone in the medial orbital wall. Related to the lacrimal sac fossa. Lies anterior to the orbital plate of ethmoid.

02Where does the nasolacrimal duct open?
SUGGESTED ANSWER

Into the inferior nasal meatus.

03Is the lacrimal gland located in this bone's fossa?
SUGGESTED ANSWER

No. The lacrimal sac is medial; the lacrimal gland lies superolaterally in the orbit in a fossa of frontal bone.
