Transmucosal Electrical Stimulation of Laryngeal Muscles
Annals of Otology, Rhinology & Laryngology, 1989A new technique is described that enables discrete activation of individual laryngeal muscles by electrical stimulation across overlying mucosa. In 15 dogs, we defined six distinct motor points by transmucosal stimulation at 3 mA while observing the resulting characteristic position of the arytenoid and true vocal cord.

Multi-MUP analysis of laryngeal muscles
Clinical Neurophysiology, 2002We performed quantitative motor unit potential (MUP) analysis of the thyroarytenoid (TA) and cricothyroid (CT) muscles, using multi-MUP-analysis in 40 healthy volunteers. The method is well tolerated, easy to perform, and examination of one muscle takes 5-10min. The mean MUP amplitude of both muscles was significantly larger in men than in women.

Single-fiber electromyography of the laryngeal muscles
Muscle & Nerve, 1999 Single-fiber electromyography (SFEMG) is useful in the evaluation of disorders of neuromuscular transmission and the assessment of motor unit morphology. Standard EMG techniques are used routinely in the evaluation of laryngeal dysfunction, but the feasibility of laryngeal SFEMG has not been established.

Changes in neurotrophic factors of adult rat laryngeal muscles during nerve regeneration
Neuroscience, 2016 Injury to the recurrent laryngeal nerve (RLN) leads to the loss of ipsilateral laryngeal fold movement, with dysphonia, and occasionally dysphagia.

Somatotopy of the extrinsic laryngeal muscles in the human sensorimotor cortex
Behavioural Brain Research, 2014 The larynx is the major organ of vocalization. The intrinsic laryngeal muscles modify the internal shape of the larynx while the extrinsic laryngeal muscles move the entire larynx vertically in the airway.

Combined Action of Laryngeal Muscles
Acta Oto-Laryngologica, 1969In the lightly halothane anesthetized dog the cricothyroid and posterior crico-arytenoid muscles are active simultaneously. With electrical stimulation of the cricothyroids, laryngeal resistance is increased and cross sectional area of the larynx decreased. With electrical stimulation of the posterior crico-arytenoids, laryngeal resistance is decreased
