Obturator nerve

STRUCTURE & FUNCTION

Understand what you see.

Chief nerve of the medial thigh adductor compartment.

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. Lumbar plexus branch
  2. Traverses obturator canal
  3. Branches around adductor brevis
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.

03 / VIVA PRACTICE

Think first. Then reveal.

Say your answer aloud before opening the suggested response.

01How do you identify obturator nerve?
SUGGESTED ANSWER

Lumbar plexus branch. Traverses obturator canal. Branches around adductor brevis.

02What separates its anterior and posterior branches?
SUGGESTED ANSWER

Adductor brevis is a useful relation, with branching variation.

03Does it supply every adductor?
SUGGESTED ANSWER

No. Pectineus is commonly femoral supplied and the hamstring part of magnus is tibial-division sciatic supplied.

04What is its main functional or developmental significance?
SUGGESTED ANSWER

Chief nerve of the medial thigh adductor compartment. Key structures to recognise: L2–L4 anterior divisions; Anterior branch; Posterior branch.
