Cervical sympathetic trunk

STRUCTURE & FUNCTION

Understand what you see.

Sympathetic pathway for head and neck structures.

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.

  • Posterior to carotid sheath
  • Superior, middle and inferior ganglia
  • Periarterial plexuses
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 cervical sympathetic trunk 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. Sympathetic pathway for head and neck structures.

02What defines Horner syndrome?
SUGGESTED ANSWER

Ipsilateral ptosis and miosis, with anhidrosis varying by lesion site.

03Do sympathetic fibres synapse in the ciliary ganglion?
SUGGESTED ANSWER

No. They pass through; head sympathetic synapses are chiefly in the superior cervical ganglion.

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

Posterior to carotid sheath; Superior, middle and inferior ganglia; Periarterial plexuses. Sympathetic pathway for head and neck structures. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
