gastrocnemius muscle of a frog (L=3.2cm in situ) was used in experiment 1 and 2‚ while a right gastrocnemius muscle of a frog (L=3.4cm in situ) was used in experiment 3. The sciatic nerve of the frog was placed over the stimulatory electrodes covered with a piece of a Kimwipe moistened with Ringer’s solution. The relationship between muscle length‚ force production and velocity of contraction was studied. Force transduced calibration In order to get a more accurate data from force transducer‚ a

MECHANICAL PROPERTIES OF SKELETAL MUSCLE USING FROG GASTROCNEMIUS AIM The purpose of this experiment was to demonstrate the physiological as well as mechanical properties of skeletal muscle using the gastrocnemius muscle of a frog by exploring five different investigations namely the single twitch‚ the graded response‚ the relationship between muscle length and tension‚ muscle tetanus‚ and muscle fatigue. These individual experiments aim to explore the way muscles can contract when an electrical stimulus
