Skeletal Muscle Physiology: Frogs & Human Subjects (1‚ 2‚ 5-8‚ 10-12‚ 14-16) 1. There is a greatr concentration of Na+ f ; there is a greater concentration of K+ e . When the stimulus is delivered‚ the ermeability of the membrane at that point is changed; and c ‚ initiating the depolarization of the membrane. Almost as soon as the depolarization wave has begun‚ a repolarization wave follows it across the membrane. This occurs as b . Repolarization restores the h of the resting cell membrane

the summation started at 16Hz‚ and it reached tetanus at 64Hz‚ for the optimal length‚ we did not get enough time to finish it‚ and it should be somewhere higher then 35 mm. Introduction: Introduction: Methods: First‚ we needed to prepare the frog by remove the skin from the leg and cut off the muscle on the femur‚ and find the gastrocnemius muscle‚ which is the big muscle on the lower leg‚ and then we found the tendon of Achilles that is below the heel‚ and cut it at the lowest point of the

Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

The purpose of this experiment is to study the effects of Ca2+ channel blockers in muscle contraction by observing the effects of injecting it in frog legs. Since calcium channel blockers‚ block the Ca2+ channels‚ inhibiting the calcium from binding to troponin‚ which exposes the myosin binding site‚ we hypothesize that the muscle fibers will not be able to contract to the same extent and therefor

Results A left 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

Lab Report 6: Respiratory Physiology Purpose: To describe the effects of carbon dioxide concentration on blood pH. Hypothesis: If the blood CO2 levels increase‚ the pH will decrease. Materials and Procedures: Materials: Willing subject (someone complete the activities of the experiment) Timer (with a second hand) Glass Urinary and Salivary pH (litmus) paper Drinking straw Procedures: 1. Measure 2 ounces of water in a glass. Obtain the pH of the

This experiment‚ Cardiovascular Fitness‚ produced the results of the fitness and fitness index of an athlete versus a non- athlete. To do so both the athlete and non-athlete had to preform the step test in which they stepped up and down the stairs at the same pace for the same duration of time. The hypothesis made by my group was that the athlete would have a lower heart-rate and better fitness index then the non-athlete. We guessed this base on the fact that many youth in America who aren’t athletes

CARDIOVASCULAR SYSTEM The Cardiovascular system consists of the cardio -heart and the vessels that carry blood to all parts of the body. If this system does not work properly then oxygen‚ hormones‚ water‚ nutrients and wastes won’t reach their target destinations. 5 liters of blood in body.
