Question 2 of 32 3. Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. Predict Question 2: In order to produce sustained muscle contractions with. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. A laboratory technician withdraws a blood sample from a vein in your upper arm knowing that You correctly answered: b.
Your answer: Membrane permeability to sodium is very low because there are only a few sodium leak channels. In resting skeletal muscle, calcium is stored in c. The tracings on the oscilloscope below were from PhysioEx Exercise 2: Skeletal Muscle Physiology, Activity 2: The Effect of Stimulus Voltage on Skeletal Muscle Contraction. After you click Submit Data, the slide will automatically be placed in the biohazardous waste disposal. To obtain an accurate spectrophotometric measurement of the glucose concentration in the sample You correctly answered: d.
Explain where the epitope antigenic determinant is located. Question 28 of 32 3. Calculate the oxygen consumption per hour for this rat using the following equation. The term motor unit refers to Your answer : b. Week 5 Quiz The Endocrine and Lymphatic Systems Part 1 of 6 - 24. Describe how a positive result is detected in this serological test.
How well did the results compare with your prediction? The membrane is more permeable to potassium because of the higher number of potassium leak channels. Stimulus frequency refers to You correctly answered: b. The thyroidectomized Tx rat is You correctly answered: a. As the stimulus increased the muscle tension also increased but not in proportion. After you click Submit Data, the slide will automatically be placed in the biohazardous waste disposal. We consider only the total amount paid in a given year.
Your answer: If extracellular K+ is increased then the intracellular K+ will decrease. When a skeletal muscle is repetitively stimulated, twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch. Rename this document to include your first and last name prior to submitting, e. Exercise 9: Renal System Physiology: Activity 1: The Effect of Arteriole Radius on Glomerular Filtration Lab Report Pre-lab Quiz Results You have not completed the Pre-lab Quiz. Question 13 of 32 3. Feedback: Learning Objective: Describe how the human body excretes excess glucose.
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. So if a bond is quoted at 88. After you click Submit Data, the slide will automatically be placed in the biohazardous waste disposal. Wave summation is achieved by You correctly answered: a. During the latent period for an isometric contraction c. Your answer: Follow a controlled diet to keep the glucose readings in at normal levels and exercise regularly. These values indicate impaired glucose uptake by cells.
The hypophysectomized Hypox rat is You correctly answered: a. This phenomenon is known as You correctly answered: c. The infectious form of Chlamydia that is spread from person to person is the You correctly answered: d. Does the force generated by the muscle change with each additional stimulus? Which of the following statements is true? I can assess with certainty the patients conditions because Type1 is if the pancreas is not producing sufficient insulin and Type 2 is if the cells in the body are unresponsive to circulating insulin. Exercise 2: Skeletal Muscle Physiology: Activity 2: The Effect of Stimulus Voltage on Skeletal Muscle Contraction Lab Report Pre-lab Quiz 1.
Drag the last slide negative control to the fluorescent microscope. The two variables that affect the rate of diffusion are: A. What is a glucose standard curve, and why did you need to obtain one for this experiment? The healthcare provider will inform him that You correctly answered: c. Submit this completed document by the assignment due date found in the Syllabus. What is your determination regarding reducing the taxable amount of income for both a and b above? Question 7 of 32 3. The normal rat will become hyperthyroidic and develop a goiter. Pre-lab Quiz Results You scored 100% by answering 5 out of 5 questions correctly.
Question 27 of 32 3. Name each phase of a typical muscle twitch, and, on the following line, describe what is happening in each phase. Exercise 2: Skeletal Muscle Physiology: Activity 2: The Effect of Stimulus Voltage on Skeletal Muscle Contraction Lab Report Pre-lab Quiz 1. As the stimulus frequency increases, the muscle force generated by each successive stimulus will first increase and then decrease as the stimulus frequency becomes very high. You answered: 1 elementary bodies 18. Question 15 of 32 0. Acetylcholine is the chemical signal the nerve sends to the muscle to cause contraction.
