Evidence of differences in the fibers of the inferior rectus muscle of the frog as regards the type of its electrical activity was obtained by a microelectrophysiological method. A constant tonic activity, consisting of polymorphic postsynaptic potentials, was observed in most fibers. Individual fibers...
The kinetics of water replacement with heavy water (deuterium oxide) in the gastrocnemius and sartorius muscles of the frog under isotonic conditions, studied both gravimetrically and by infrared photometry, reveals three water compartments: (i) non-exchangeable (≈ 80 ml/kg fresh weight), (ii) ...
1. The properties of pyruvate kinase and, if present, phosphoenolpyruvate carboxykinase from the muscles of the sea anemone, scallop, oyster, crab, lobster and frog were investigated. 2. In general, the properties of pyruvate kinase from all muscles were similar, except for those of the enzyme...
METHODS Muscles, together with their nerves and appropriate spinal roots, were dissected from summer and winter frogs of the species Rana pipiens and R. ca... SW Kuffler,EMV Williams - 《Journal of Physiology》 被引量: 509发表: 1953年 Auditory and vocal nuclei in the frog brain concentrate ...
Sexual Dimorphism in Mass of the Hindlimb Muscles of the Piebald Odorous Frog(Odorrana schmackeri) 来自 掌桥科研 喜欢 0 阅读量: 142 作者:L Zhang,Y Zhao,L Shi,X Chen,LU Youqiang,LiangQIAO 摘要: Male-biased sexual dimorphism in hind limb muscles is widespread in anuran species where ...
Abdominal hypaxial muscles of male anurans function in vocalization by causing forcible expulsion of pulmonary air through the larynx. The hypaxial muscles were studied in the leopard frog, Rana pipiens, to test whether functions of these muscles in males are reflected in sexual dimorphism and in ...
1. A resting sartorius muscle of the frog or toad possesses a special kind of elasticity which is shown to be due to a component lying between the two sets of filaments. The elastic effect is seen only for very small length changes, up t... DK Hill - 《Journal of Physiology》 被引量...
Cain, Infante and Davies (1962) observed a breakdown of ATP in single tetanic contractions of frog rectus abdominis muscle poisoned with 1-fluoro-2,4-dinitrobenzene (FDNB). As the phosphorylcreatine (PC) of these muscles hardly changes, the facts are explained by an inhibibion of the creatin...
The Extracellular Space of Voluntary Muscle Tissues The volume occupied by the extracellular space has been investigated in six types of voluntary muscles: sartorius (frog), semitendinosus (frog), tibialis anticus longus (frog), iliofibularis (frog), rectus abdominis (frog), and diaphragm... GN...
In mammals, the epaxial muscles are believed to stabilize the trunk during walking and trotting because the timing of their activity is not appropriate to produce bending of the trunk. To test whether this is indeed the case, we recorded the activity of the m. multifidus lumborum and the m...
