Origin

The bronchial filament of the left recurrent laryngeal nerve is a branch of the left recurrent laryngeal nerve.

Course

The bronchial filament of the left recurrent laryngeal nerve emerges from the left recurrent laryngeal nerve as it wraps underneath the aortic arch. From here it descends either anterior or posterior to the left pulmonary artery to reach the left posterior pulmonary plexus.

Branches

There are no named branches of the bronchial filament of the left recurrent laryngeal nerve.

Supplied Structures & Function

The parasympathetic efferent innervation to the left lung allows for contraction of bronchial smooth muscle and increased mucus secretion in airways. Autonomic afferent innervation relays sensory feedback relating to pain, irritants, and stretch.
