Abstract Präparation einer Einzelfaser des M. semitendinosus des Frosches. Elektrische Reizung des Muskels mit unterschiedlichen Reizstärken ergibt unterschwellige, überschwellige und tetanische Reizantworten. Experimentelle Demonstration der Länge-Kraft-Beziehung (Diagramm). Zusammenhang mit der Lagebeziehung der Muskelfilamente (Trick). Experiment zur Verkürzungsgeschwindigkeit-Last-Beziehung des Muskels (Diagramm). Elektronenmikroskopische Aufnahmen des Muskelsarkomers.
A single muscle cell is dissected out of the m. semitendinosus from the frog's leg. Demonstration of the threshold stimulus and response behaviour, two single contractions superimposed on one another and a tetanus, experimental determination of the length-force relationship and the relationship between speed of contraction and load.
