In the distance, the man sees a spiralling beacon of light. Behind him, the island's lone oak tree groans slightly in the wind and crackles with…

Maximum contractile force production dependant on muscle and sarcomere length in isolated sartorius muscle of Rhinella marina Abstract: An isolated Sartorius muscle of Rhinella marina was repeatability stimulated with electrical impulses to induce isometric contraction. Contractile forces evoked were measured with a force transducer and the relationship between force and muscle length was investigated through the modulation of sample lengths from 80%-140% of the sample resting length. The data…
