Cervical plexus
Understand what you see.
Supplies neck skin and muscles and contributes to the phrenic nerve.
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 cervical plexus 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. Supplies neck skin and muscles and contributes to the phrenic nerve.
02Name cutaneous branches.+
Lesser occipital, great auricular, transverse cervical and supraclavicular nerves.
03State phrenic roots.+
C3–C5, principally C4; the cervical plexus contribution should not be confused with the whole brachial plexus.
04Point out three important relations and explain their significance.+
C1–C4 anterior rami; Posterior border of SCM; Cutaneous and muscular branches. Supplies neck skin and muscles and contributes to the phrenic nerve. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
