long thoracic nerve


long tho·rac·ic nerve

[TA] arises from the fifth, sixth, and seventh cervical nerves (roots of brachial plexus), descends the neck behind the brachial plexus, and is distributed to the serratus anterior muscle; it is somewhat unusual in that it courses on the superficial aspect of the muscle it supplies; its paralysis results in "winged scapula." Synonym(s): nervus thoracicus longus [TA], Bell respiratory nerve, external respiratory nerve of Bell, posterior thoracic nerve
