The relationship between the accessory muscle activity (sternohyoid and sternothyroid) and respiration was studied in canines. These animals do not have an omohyoid muscle such as found in primates. Therefore, chair-trained monkeys that have all three accessory muscles were used in a portion of the study. Findings in canines supported those previously reported. The sternothyroid muscle fired spontaneously with the onset of inspiration, but there was no similar activity in the sternohyoid. The activity of both muscles was observed after sectioning the recurrent laryngeal nerves and inducing hypoxia and hypercarbia. The severely hypoxic animals produced some negligible activity in the sternohyoid muscle. The data obtained from the chair-trained monkeys showed no consistent accessory muscle activity during normal respiration with recordings taken immediately after electrode placement, at 24 hours, and one week later. Respiratory activity was consistent in the omohyoid and sternothyroid but not in the sternohyoid muscle when partial airway obstruction and hypoxia were induced.
在犬类动物中研究了辅助肌肉活动（胸骨舌骨肌和胸骨甲状肌）与呼吸之间的关系。这些动物没有像灵长类动物那样的肩胛舌骨肌。因此，在部分研究中使用了训练有素、具有全部三块辅助肌肉的猴子。犬类动物的研究结果支持了先前报道的结果。胸骨甲状肌在吸气开始时自发放电，但胸骨舌骨肌没有类似活动。在切断喉返神经并诱发缺氧和高碳酸血症后，观察到了这两块肌肉的活动。严重缺氧的动物在胸骨舌骨肌中产生了一些可忽略不计的活动。从训练有素的猴子获得的数据显示，在电极放置后立即、24小时和一周后进行记录时，正常呼吸期间没有一致的辅助肌肉活动。当诱发部分气道阻塞和缺氧时，肩胛舌骨肌和胸骨甲状肌的呼吸活动是一致的，但胸骨舌骨肌则不然。
