Plan of lumbar plexus (accessory obturator visible at bottom left).
The lumbar plexus and its branches (accessory obturator visible at bottom left).
|Latin||Nervus obturatorius accessorius|
|Anatomical terms of neuroanatomy|
It is of small size, and arises from the ventral divisions of the third and fourth lumbar nerves. Recent evidence support that this nerve arises from Dorsal divisions.
Occasionally the accessory obturator nerve is very small and is lost in the capsule of the hip-joint.
When it is absent, the hip-joint receives two branches from the obturator nerve.
