Mapping the compound muscle action potentials of cricothyroid muscle using electromyography in thyroid operations: a novel method to clinically type the external branch of the superior laryngeal nerve.

30 Jul 2009 OBJECTIVE: Variations of the external branch of the superior laryngeal nerve (EBSLN) are well represented in literature but with conflicting reports about the types and variations. Using EMG, the cricothyroid compound muscle action potential (CMAP) ... Read more...

Characteristics of glottic closure reflex in a canine model.

21 Jun 2009 PURPOSE: The most important function of the larynx is airway protection which is provided through a polysynaptic reflex closure triggered by the receptors in the glottic and supraglottic mucosa, evoking the reflex contraction of the laryngeal ... Read more...

Effects of dopamine D1 and D2 receptor antagonists on laryngeal neurophysiology in the rat.

15 Jun 2009 Hypophonia is an early symptom in Parkinson's disease (PD) that involves an increase in laryngeal muscle activity, interfering with voice production. Our aim was to use an animal model to better understand the role of different dopamine receptor ... Read more...

Technical information about 'Laryngeal Nerves'

Definition: Branches of the VAGUS NERVE. The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibers to the cricothyroid muscles, and internal branches, which carry sensory fibers. The RECURRENT LARYNGEAL NERVE originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.
