This break is a sudden gap in sound which occurs when the thyroarytenoid muscles suddenly decrease their activity and the cricothyroid muscles begin to function.
12.
Its innervation is by the recurrent laryngeal nerve ( from vagus ) just like all the intrinsic muscles of the larynx except the cricothyroid muscle.
13.
This figure demonstrates control of the position or " tilt " of the thyroid cartilage through engagement or disengagement of the cricothyroid muscle.
14.
In an emergency a Cricothyrotomy can be used by health care professionals, where an airway is inserted through a surgical opening in the cricothyroid membrane.
15.
The recurrent laryngeal nerves provide motor control for all external muscles of the larynx except for the cricothyroid muscle, which also runs along the posterior thyroid.
16.
Improved voice training methods ( which often produce better results than the surgery ) and the inherent risks of vocal surgery have largely eliminated the demand for cricothyroid approximation.
17.
The "'median cricothyroid ligament "'is a flat band of white connective tissue that connects the front parts of the contiguous margins of the cricoid and thyroid cartilages.
18.
Several manufacturers market prepackaged cricothyrotomy kits, which enable one to use either a wire-guided percutaneous dilational ( Seldinger ) technique, or the classic surgical technique to insert a polyvinylchloride catheter through the cricothyroid membrane.
19.
The larynx is held in one hand by the practitioner while the other hand is holding a blade to incise the skin through the subcutaneous tissue and into the midline of the cricothyroid membrane to access the trachea.
20.
A cricothyrotomy is an incision made through the skin and cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by a foreign body, angioedema, or massive facial trauma.
