The two recurrent nerves Fig. 341. are not quite symmetrical at their origin. Tliat of the right side is detached from the pneumogastric below the axillary artery, nearly at the dorso-cervical arterial trunk. It is immediately reflected forward in embracing the origin of that trunk, which it crosses inwards to be placed against the trachea, in the middle of the prin- cipal cardiac nerves, with some of which it contracts intimate adherences. On the left side, it is only when the pneumogas- tric nerve arrives near the root of the lung that it gives off its recurrent. To be reflected forward, the latter turns from left to right behind the arch of the aorta, and arrives be- neath the inferior face of the ti'achea, among the cardiac nerves, with which it communicates like tlie DISTRIBUTION OF THE NERVES IN THE LARYNX OF THE Tight.
