Vagus nerve

Locate vagus nerve on this anatomical reference. Read the original plate labels to confirm the view and adjacent structures.

Zoom in, then drag to inspect. Keyboard: + / − to zoom, arrows to pan, 0 to reset. Tap the numbered markers to explore parts.

Nerves & ganglia

Superior laryngeal nerve

STRUCTURE & FUNCTION

Understand what you see.

Divides into sensory internal and mainly motor external branches.

Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.

01 / IDENTIFICATION

How to recognise it.

  1. Identify by its course and target
  2. Distinguish sensory, motor and autonomic components
  3. Confirm its skull-base exit or spinal origin
02 / KEY STRUCTURES

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.

Related features & study points (3)

Additional relations, attachments or microscopic details to revise alongside this plate. These are separate from its numbered image landmarks.

  • Vagus branch
  • Internal laryngeal branch
  • External laryngeal branch
03 / VIVA PRACTICE

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 superior laryngeal nerve and give its main role.
SUGGESTED ANSWER

Identify by its course and target. Distinguish sensory, motor and autonomic components. Confirm its skull-base exit or spinal origin. Divides into sensory internal and mainly motor external branches.

02Contrast the two branches.
SUGGESTED ANSWER

Internal branch supplies sensation chiefly above vocal folds and passes through thyrohyoid membrane. External branch supplies cricothyroid.

03Which artery accompanies the internal branch?
SUGGESTED ANSWER

Superior laryngeal artery through the thyrohyoid membrane.

04Point out three important relations and explain their significance.
SUGGESTED ANSWER

Vagus branch; Internal laryngeal branch; External laryngeal branch. Divides into sensory internal and mainly motor external branches. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
