Recurrent laryngeal nerve
Recurrent laryngeal nerve (RLN, nervus laryngeus recurrens): vagus nerve branch supplying the larynx's intrinsic muscles; right loops under the subclavian artery, left under the aortic arch; injury is a key thyroidectomy complication.
Superior laryngeal nerve
Superior laryngeal nerve (nervus laryngeus superior), a vagus nerve branch dividing into an internal sensory branch to the supraglottic larynx and an external motor branch to the cricothyroid muscle; injury causes pitch-range loss and dysphagia.
Vagus nerve
Vagus nerve (cranial nerve X): longest cranial nerve, medulla to abdomen, sensory and parasympathetic fibers. Also covers vagus nerve stimulation, FDA-approved uses, and evidence quality.
Vocal cord paresis
Vocal cord paresis, or vocal fold paresis, is partial weakness of a vocal fold from incomplete laryngeal nerve denervation, between normal function and full paralysis; it causes glottic insufficiency, breathy voice, and is diagnosed with laryngoscopy plus laryngeal EMG.
