Ophthalmic division (V1)
Understand what you see.
Sensory division supplying forehead, cornea and related upper facial regions.
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 by its course and target
- 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 ophthalmic division (v1) 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. Sensory division supplying forehead, cornea and related upper facial regions.
02State the corneal-reflex limbs.+
Afferent limb is chiefly nasociliary V1; efferent blink is VII to orbicularis oculi.
03Does V1 carry motor fibres to muscles of mastication?+
No. Those fibres travel with V3.
04Point out three important relations and explain their significance.+
Trigeminal ganglion; Superior orbital fissure; Frontal, lacrimal and nasociliary branches. Sensory division supplying forehead, cornea and related upper facial regions. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
