Semicircular canals
Understand what you see.
Detect angular acceleration through the membranous semicircular ducts.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Three roughly perpendicular bony canals
- Membranous ducts lie inside
- Ampullae contain cristae
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 semicircular canals and give its main role.+
Three roughly perpendicular bony canals. Membranous ducts lie inside. Ampullae contain cristae. Detect angular acceleration through the membranous semicircular ducts.
02Where are the receptor hair cells?+
In the crista ampullaris of each membranous ampulla; their processes project into the cupula.
03Do they primarily detect static gravity?+
No. Utricle and saccule are the principal otolith organs for gravity and linear acceleration.
04Point out three important relations and explain their significance.+
Anterior canal; Posterior canal; Lateral canal. Detect angular acceleration through the membranous semicircular ducts. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
Read the references.
Credited anatomical plates, microscopy and university teaching references. Individual image credits appear below the viewer. Historical plates can use older terminology; use the lesson text for current names.
