MEDIVEERSETHE PRACTICAL HUB
Identify its root on the inferior brain reference, then trace its extracranial course using the relationship map. Distinguish sensory, motor and autonomic components. Confirm its skull-base exit or spinal origin.
Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.

Abducens nerve (VI)
Understand what you see.
Motor supply to lateral rectus.
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.
- Identify its root on the inferior brain reference, then trace its extracranial course using the relationship map
- Distinguish sensory, motor and autonomic components
- Confirm its skull-base exit or spinal origin
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 abducens nerve (vi) and give its main role.+
Identify by its course and target. Distinguish sensory, motor and autonomic components. Confirm its skull-base exit or spinal origin. Motor supply to lateral rectus.
02What movement is weakened by VI palsy?+
Abduction of the eye, often producing horizontal diplopia.
03Where is VI in the cavernous sinus?+
It runs within the sinus beside the internal carotid artery, rather than in the lateral wall with III, IV, V1 and V2.
04Point out three important relations and explain their significance.+
Pontomedullary junction; Cavernous sinus; Superior orbital fissure. Motor supply to lateral rectus. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
