Among 30 so-called accessory respiratory and other muscles tested, the presence of rhythmic respiratory impulses was found in 12. Both expiratory and inspiratory impulses were detected in certain muscles, in others only in- or expiratory ones. The muscles with most frequent inspiratory impulses were the intercartilaginous intercostal muscles, the intrinsic muscle of the larynx and the nostril; those with expiratory impulses were abdominis, external and internal oblique, transversus abdominis, scalenus anterior, and lower interosseous intercostal muscles.

1. A surface electrode was used to record electromyographic activity of the posterior crico-arytenoid muscle during breathing in normal subjects and patients with airflow obstruction. 2. Phasic activity of the posterior crico-arytenoid muscle was demonstrated. This was present on inspiration and absent on expiration. 3. Phasic inspiratory activity in normal subjects was present only during periods of voluntary hyperventilation, increasing with tidal volume, whereas in patients with airflow obstruction inspiratory activity was present even during resting breathing and failed to increase further during voluntary hyperventilation. 4. The posterior crico-arytenoid muscle may be considered as an inspiratory muscle acting analogously to other accessory respiratory muscles.

The postmortem diagnosis of drowning death and understanding the mechanisms leading to drowning require a comprehensive judgment based on numerous morphological findings in order to determine the pathogenesis and epidemiological characteristics of the findings. Effortful breathing during the drowning process can result in intramuscular hemorrhage in respiratory and accessory respiratory muscles. However, the characteristics of this phenomenon have not been investigated. We analyzed the epidemiological characteristics of 145 cases diagnosed as drowning, in which hemorrhage, not due to trauma, was found in the respiratory muscles and accessory respiratory muscles. Hemorrhage was observed in 31.7% of these cases, and the incidence did not differ by gender or drowning location. The frequency of hemorrhage was significantly higher in months with a mean temperature below 20°C than in months above 20°C, suggesting a relationship between the occurrence of hemorrhage and low environmental temperature. Moreover, the frequency of hemorrhage was significantly higher in the elderly (aged ≥65 years) compared to those <65 years old. In the elderly, the weakening of muscles due to aging may contribute to the susceptibility for intramuscular hemorrhage. Moreover, these intramuscular hemorrhages do not need to be considered in cases of a potential bleeding tendency due to disease such as cirrhosis or medication such as anticoagulants. Our results indicate that intramuscular hemorrhage in respiratory and accessory respiratory muscles can serve as an additional criterion to differentiate between fatal drowning and other causes of death, as long as no cutaneous or subcutaneous hematomas above the muscles with hemorrhages are observed. In addition, the epidemiological features that such intramuscular hemorrhage is more common in cold environments and in the elderly may provide useful information for the differentiation.
