When someone wants to solve a problem or present new… 677 Words 3 Pages Exercise 2: Skeletal Muscle Physiology: Activity 4: Tetanus in Isolated Skeletal Muscle Lab Report Pre-lab Quiz Results You scored 100% by answering 3 out of 3 questions correctly. Most of the tubular filtrate is reabsorbed to prevent fluid loss and maintain homeostasis.
Pressure will increase and filtration rate will decrease. At any point in which the bicep muscle remains at a fixed length. The thyroidectomized Tx rat is You correctly answered: a. How did the frequency of stimulation affect the amount of force generated by the isolated skeletal muscle when the frequency of stimulation was increased such that the muscle twitches did not fully relax between subsequent stimuli? How well did the results compare with your predictions? Stimulus frequency refers to You correctly answered: b. Which of the following would not result in a decrease in the blood vessel radius? Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Employment Levels Regardless of where we are, unemployment occurs and. The normal rat will become hypothyroidic and develop a goiter.
At that stage the muscle becomes fatigued and contractile force starts to decrease over a period of time. The goal of the exercise is to provide a simulation for the process of the facilitated diffusion of… 1049 Words 5 Pages Exercise 2: Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. The new policy should be a great way to manage both business and end-user expectations. The hypophysectomized Hypox rat is You correctly answered: a. How would you interpret these results? Explain why this might occur. Now that you have calculated the oxygen consumption per hour for this rat, you can calculate the metabolic rate per kilogram of body weight with the following equation note that you need to convert the weight data from grams to kilograms to use this equation.
Hint: Look at the relationship of the variables in the equation. Which of the following processes does not occur during inspiration? Drag the next slide positive control to the fluorescent microscope. None of the rats developed a goiter with this injection. When a skeletal muscle is repetitively stimulated, twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. These values indicate diabetes mellitus. Question 28 of 32 3.
Your answer: Patients one and five were in the diabetic range. It is a type of diffusion. What is the approximate concentration of K+ outside a cell extracellular concentration? Each new copy of the PhysioEx 9. However, our data center has a problem. This is because the customer can still cancel and get a refund.
Feedback: Please review chapter 17. Are these results called treppe or wave summation? Williams, Shira Dunsiger, Joseph T. Students are also asked to make predictions about the results for an experiment to apply what they have learned before seeing the results. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. The temperature of the solutions and the difference in concentration of the ion or molecule between the sides of the membrane 2. Active force data changes as the resting length of the muscle changes. The normal rat will become hypothyroidic and develop a goiter.
Which of the membranes can it pass through? The graded depolarization in the skeletal muscle fiber that is elicited in response to one action potential from the motor neuron is called Your answer: a. Wave summation increases the force produced in the muscle. Drag the first slide patient A to the fluorescent microscope. Which of the following is not a phase of a skeletal muscle twitch? During moderate aerobic exercise, which…. Your answer: She likely has gestational diabetes. Question 13 of 32 3.
A twitch is You correctly answered: a. The larger radius, the greater laminar flow. How would you interpret these results? Question 6 of 32 3. Aldosterone results in increased sodium and water reabsorption and increased potassium secretion. Match each of the definitions in Column A with the appropriate term in Column B. Is this called treppe or wave summation? Yes, changing the stimulus voltage will change the latent period duration proportionately. Lighter the weight the muscle is contracted quicker in both latent and velocity.
