The Larynx Flashcards

1
Q

Describe the route taken by the recurrent laryngeal nerves?

A

Right - passes around the subclavian
Left - passes around the arch of the aorta

Ascends the neck, lying between the trachea and oesophagus, before passing under the inferior constrictor of the pharynx to meet the larynx
