long thoracic nerve

(redirected from Long thoracic)

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."

long thoracic nerve

one of a pair of supraclavicular branches from the roots of the brachial plexus. It arises by three roots, from the fifth, the sixth, and the seventh cervical nerves. The fibers from the fifth and the sixth cervical nerves join just after they pierce the scalenus medius and are united with the fibers from the seventh cervical nerve at the level of the first rib. Compare phrenic nerve.
