Auricle (pinna)
Understand what you see.
Collects sound into the external acoustic meatus.
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.
- External cartilaginous ear
- Helix surrounds antihelix
- Lobule lacks cartilage
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 auricle (pinna) and give its main role.+
External cartilaginous ear. Helix surrounds antihelix. Lobule lacks cartilage. Collects sound into the external acoustic meatus.
02Which cranial nerve supplies its small muscles?+
Facial nerve VII supplies auricular muscles; sensory innervation is mixed and includes great auricular, lesser occipital, auriculotemporal and auricular vagal branches.
03Why does the lobule feel different?+
It contains fibrofatty tissue rather than the elastic cartilage supporting most of the auricle.
04Point out three important relations and explain their significance.+
Helix; Antihelix; Concha. Collects sound into the external acoustic meatus. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
