External Laryngeal Nerve

The external laryngeal nerve is the smaller, external branch (ramus externus) of the superior laryngeal nerve. It descends on the larynx, beneath the sternothyroid muscle, to supply the cricothyroid muscle.

It functions to tense the vocal cords by activating the cricothyroid muscle, increasing pitch.

It gives branches to the pharyngeal plexus and the superior portion of the inferior pharyngeal constrictor, and communicates with the superior cardiac nerve behind the common carotid artery.

Famous quotes containing the words nerve and/or external:

    our nerve filaments twitch with its presence
    day and night,
    nothing we say has not the husky phlegm of it in the saying,
    nothing we do has the quickness, the sureness,
    the deep intelligence living at peace would have.
    Denise Levertov (b. 1923)

    When a person hasn’t in him that which is higher and stronger than all external influences, it is enough for him to catch a good cold in order to lose his equilibrium and begin to see an owl in every bird, to hear a dog’s bark in every sound.
    Anton Pavlovich Chekhov (1860–1904)
