Virtual lab 9 Activity 2: Determining the Latent Period 1. How long is the latent period? 2.78 msec. 2. What occurs in the muscle during this apparent lack of activity? Ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack. Activity 3: Investigating Graded Muscle Response to Increased Stimulus Intensity 1. Use your graph to answer and note that the dot in the graph turns red when you select that line in the table. What is the minimal‚ or threshold

convenient way to find exercises and it was a great was to narrow down results for a specific muscle group or a sing muscle. This website is something I will definitely use in the future for my workouts. The website also had beneficial information on diets‚ nutrition‚ and weight management. Altogether the website was very easy to navigate and had a lot of helpful information. For the assignment I looked at and performed various exercises for a lot of different muscles. The exercises I watched and performed

Lab 4: Skeletal Muscle Function Exercise 5: The Length-Tension Relationship Materials and Methods In this experiment I used a frog anesthetized with ms222. The frog’s skin is cut and removed from both the legs‚ the Achilles tendon is cut and the tendon and calf muscle are removed from the lower legs. The femur muscle is also cut. Attached to the legs are femur clamps which are connected to the transducer arm‚ stimulation electrodes are then positioned against the muscle. I plugged the output

Experiment 2: Skeletal Muscle ABSTRACT Frog skeletal muscle is used as an animal model to study muscle contraction. The objectives of this experiment is to demonstrate the physiological responses of skeletal muscle to electrical stimuli using frog gastrocnemius‚ to understand twitch‚ summation‚ tetanus and fatigue‚ to investigate the relationship between initial tension and force of contraction‚ to explore the differences between human and frog skeletal muscle. The threshold voltage is 0.4V. The
