The subclavian nerve, also known as the nerve to subclavius, is an anterior branch from the C5 and C6 roots of the brachial plexus, and supplies the subclavius muscle.

Gross anatomy


The subclavian nerve is a small branch from the upper trunk of the brachial plexus that arises from the point of junction of the fifth and sixth cervical nerves.


The subclavian nerve descends anterior to the brachial plexus and subclavian vessels to innervate the subclavius muscle.


The subclavian nerve may give off an accessory phrenic nerve
