Nerves & ganglia

Pterygopalatine ganglion

STRUCTURE & FUNCTION

Understand what you see.

Parasympathetic relay for lacrimal, nasal and palatal secretomotor pathways.

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.

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 pterygopalatine ganglion 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. Parasympathetic relay for lacrimal, nasal and palatal secretomotor pathways.

02What forms the nerve of the pterygoid canal?
SUGGESTED ANSWER

Greater petrosal parasympathetic and deep petrosal sympathetic fibres join.

03Which fibres synapse in this ganglion?
SUGGESTED ANSWER

Preganglionic parasympathetic fibres; postganglionic sympathetic fibres traverse it.

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

Pterygopalatine fossa; Nerve of pterygoid canal; V2 branch distribution. Parasympathetic relay for lacrimal, nasal and palatal secretomotor pathways. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
