... performed experiments to determine whether aspects of the respiratory control system of bullfrogs, Lithobates catesbeianus , are maintained or suppressed following minimal use of air breathing in overwintering environments. Based on the necessity for control of lung ventilation in early spring, we...

...A. M. Petersen; T. T. Gleeson SUMMARY We characterized carbohydrate metabolism following activity in the American bullfrog, Rana catesbeiana , and compared whole body metabolic profiles between two seasons. Forty-eight adult male Rana catesbeiana were chronically cannulated and injected with[U- 14...

...L. W. Kline; M. L. Zhang; P. K. T. Pang ABSTRACT Cholecystokinin octapeptide (CCK), acetylcholine (ACh) and ceruletide have been shown to produce contraction in bullfrog ( Rana catesbeiana ) gallbladder strips. Agents capable of relaxing the bullfrog gallbladder are less numerous. Calcitonin gene...

..., contributes to the control of breathing pattern. This study tested the hypothesis that the NI plays a critical role in breathing pattern formation in the bullfrog. More specifically, we postulated that this nucleus was the site responsible for clustering breaths into distinct episodes of breathing...
