How to recognise it.
- Stirrup-shaped medial ossicle
- Two crura and a footplate
- Footplate occupies oval window
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.
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 stapes and give its main role.+
Stirrup-shaped medial ossicle. Two crura and a footplate. Footplate occupies oval window. Transmits vibration into inner-ear fluid.
02Which nerve supplies stapedius?+
A branch of facial nerve VII. Injury proximal to this branch may cause hyperacusis.
03What holds the footplate at the oval window?+
The annular ligament allows movement while sealing the margin.
04Point out three important relations and explain their significance.+
Head; Anterior and posterior crura; Footplate. Transmits vibration into inner-ear fluid. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
