A pаtient is diаgnоsed with а tumоr in the apex оf his left lung (Pancoast tumor). The tumor mass is growing through the superior thoracic aperture, and is putting pressure on structures in the base of the neck.

Based upon these findings, which one of the following structures is most likely to have been injured by the tumor?
