Vestibule, utricle and saccule
Understand what you see.
Otolith organs detect linear acceleration and head orientation relative to gravity.
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.
- Central bony labyrinth between cochlea and canals
- Contains utricle and saccule
- Related laterally to 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 vestibule, utricle and saccule and give its main role.+
Central bony labyrinth between cochlea and canals. Contains utricle and saccule. Related laterally to oval window. Otolith organs detect linear acceleration and head orientation relative to gravity.
02What distinguishes macula from crista?+
Maculae in utricle and saccule have an otolithic membrane with otoconia. Cristae in ampullae have a cupula and respond to angular acceleration.
03Which nerve carries vestibular sensation?+
Vestibular division of VIII; primary sensory cell bodies lie in the vestibular ganglion.
04Point out three important relations and explain their significance.+
Utricular macula; Saccular macula; Otolithic membrane. Otolith organs detect linear acceleration and head orientation relative to gravity. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
