Laryngeal Nerves - Physiology
Research News and Information
Definition of 'Laryngeal Nerves'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. |

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...
Multiple forebrain systems converge on motor neurons innervating the thyroarytenoid muscle.
4 May 2009 The present study investigated the central connections of motor neurons innervating the thyroarytenoid laryngeal muscle that is active in swallowing, respiration and vocalization. In both intact and sympathectomized rats, the pseudorabies virus ... Read more...
