  • A novel accessory respiratory Muscle in the American alligator (Alligator mississippiensis)

    Abstract:

    The Muscles that effect lung ventilation are key to understanding the evolutionary constraints on animal form and function. Here, through electromyography, we demonstrate a newly discovered respiratory function for the iliocostalis Muscle in the American alligator (Alligator mississippiensis). The iliocostalis is active during expiration when Breathing on land at 28°C and this activity is mediated through the uncinate processes on the vertebral ribs. There was also an increase in Muscle activity during the forced expirations of alarm distress vocalisations. Interestingly we did not find any respiratory activity in the iliocostalis when the alligators were Breathing with their body submerged in water at 18°C, which resulted in a reduced Breathing frequency. The iliocostalis is an accessory Breathing Muscle that alligators are able to recruit in to assist expiration under certain conditions

  • monitoring Breathing Muscle performance during singing noninvasively using mechanomyography and electromyography
    Journal of Voice, 2019
    Co-Authors: Muhammad Imran Ramli, Nur Azah Hamzaid, Julia Patrick Engkasan
    Abstract:

    Abstract Objectives The aim of this study was to investigate the performance of mechanomyography (MMG) and electromyography (EMG) in monitoring the sternocleidomastoid (SCM) as accessory respiratory Muscles when Breathing during singing. Methods MMG and EMG were used to record the activity of the SCM in 32 untrained singers reciting a monotonous text and a standard folk song. Their voices were recorded and their pitch, or fundamental frequency (FF), and intensity were derived using Praat software. Instants of inhale and exhales were identified during singing from their voice recordings and the corresponding SCM MMG and EMG activities were analysed. Results The SCM MMG, and EMG signals during Breathing while singing were significantly different than Breathing at rest (p Conclusions This study established MMG and EMG as the quantitative measurement tool to monitor Breathing activities during singing. This is useful for applications related to singing therapy performance measure including potentially pathologically effected population. While the MMG and EMG could not distinguish FF and intensity significantly, it is useful to serve as a proxy of inhalation and exhalation levels throughout a particular singing session. Further studies are required to determine its efficacy in a therapeutic setting.
