Free Response Questions:
With regards to laryngeal cancer, a "breathy" voice indicates----whereas a "muffled" voice indicates----?
Quick Facts:
-All intrinsic muscles of larynx are innervated by recurrent laryngeal nerve except cricothyroid (ext. sup. laryngeal).
-Sole abductor of vocal cords is posterior cricoarytenoid.
-Path of Vagus:
-nuclei in upper medulla give rise to rootlets.
-motor fibers come from nucleus ambiguus and join at cervical ganglion below jugular foramen.
-vagus exits jugular foramen w/ CNIX and XII. It descends in carotid sheath.
-R RLN curls under subclavian artery and runs superiorly to tracheoesophageal groove, passes into larynx under inf. constrictor.
-L RLN leaves vagus at arch, loops under ligamentum arteriosum before entering groove.
