External Branch of Superior Laryngeal (Motor) Supplies fibres to cricothyroid muscle; Nerve damage - patient would be unable to tense the vocal cords
Recurrent laryngeal N Supplies Motor fibres to upper esophagus, lower pharynx, and all the laryngeal muscles except cricothyroideus.
Cricothyroid one muscle innervated by the external branch of the superior laryngeal nerve; responsible for stretching (elongating) the vocal ligament is the
Posterior cricoarytenoid only muscle that abducts the vocal folds; is innervated by the inferior laryngeal nerve
vagus nerve motor innv. to the muscles of the pharynx and larynx; supplies motor innervation to the palate muscles, with the exception of tensor veli palatini (innervated by the V3 division of the trigeminal nerve); Damage would cause problems with swallowing
glossopharyngeal nerve supplies sensory, but not motor, innervation to the pharynx
superior cervical ganglion GVE and GVA fibers to the blood vessels & glands of the pharynx
