|Anatomical terms of neuroanatomy|
The subclavian nerve or nerve to the subclavius is a small filament, which arises from the point of junction of the fifth and sixth cervical nerves. This origin is known as Erb's point.
The subclavian nerve descends to the subclavius muscle in front of the third part of the subclavian artery and the upper trunk of the brachial plexus, and is usually connected by a filament with the phrenic nerve.
