Activity in the Inner Laryngeal Muscles during Respiration

Abstract

The inner laryngeal muscles possess subtle cooperative movements to fulfill various laryngeal functions. Many assessments have been made to clarify these physiological functions, however various views not yet unified.
Laryngeal function in humans remains generally unclear despite results obtained from repeated animal experiments. However, with humans has not been easy. clarifying the physiological functions by experiments. Among current methods of study, the elec- tromyograph is considered to obtain the most potent measurements for elucidating the physiological mechanism of the inner laryngeal muscle in humans. Therefore, we assessed the problems remaining to be solved by summarizing existing findings in relation to the inner laryngeal muscle activity during respiration in humans as demonstrated by electromyographical studies reported thus far.
