Cavernous sinus

STRUCTURE & FUNCTION

Understand what you see.

Paired dural venous space with important neurovascular relations.

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 its origin or drainage
  2. Trace its regional course
  3. Confirm its important neighbouring structures
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.

  • Beside sphenoid body
  • ICA and VI within sinus
  • III, IV, V1, V2 in lateral wall
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 cavernous sinus and give its main role.
SUGGESTED ANSWER

Identify its origin or drainage. Trace its regional course. Confirm its important neighbouring structures. Paired dural venous space with important neurovascular relations.

02Which nerve is closely related to ICA within it?
SUGGESTED ANSWER

VI; III, IV, V1 and V2 occupy the lateral wall.

03Explain a possible route of facial infection spread.
SUGGESTED ANSWER

Facial/angular and ophthalmic venous communications, and deep facial/pterygoid-emissary pathways, can communicate with intracranial venous channels.

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

Beside sphenoid body; ICA and VI within sinus; III, IV, V1, V2 in lateral wall. Paired dural venous space with important neurovascular relations. Use the reference plate to locate the region; the relationship map organises the associations and is not drawn to scale.
