Question 19 of 320.0/ 3.0 PointsWhich of the following is associated with the parasympathetic nervous system?A. adrenal glandsB. epinephrineC. SLUDDD. increased heart rateFeedback: This system is also known as the "rest and digest" system.
Part 11 of 14 -6.0/ 9.0 PointsQuestion 20 of 323.0/ 3.0 PointsA digital thermometer is calibrated to be accurate within +/- 0.1 ˚C. Two temperaturemeasurements are then taken that show the temperature is 24.9 ˚C and 25.1 ˚C? Do thesemeasurements agree?
B. NoC. Not enough information is givenFeedback: Correct! Yes, the measurements agree. Based on the accuracy of the thermometer, the24.9 ˚C measurement indicates the temperature can be 24.8 ˚C and 25.0 ˚C and the 25.1 ˚Cmeasurement indicates the temperature can be 25.0 ˚C and 25.2 ˚C. The two measurementstogether tell us that the temperature is 25.0 ˚C.Question 21 of 323.0/ 3.0 PointsWhat does accuracy refer to when discussing data measurement?
Question 22 of 320.0/ 3.0 PointsIn data measurement, what does precision refer to?
A. How close a measured value is to previous measured valuesB. The number of significant digits in the solution of a mathematical problemC. Whether or not a measurement was performed correctly.D. How close a measured value is from a standard or established valueFeedback: Accuracy refers to how close a measured value is from a standard or establishedvalue.Part 12 of 14 -21.0/ 21.0 PointsQuestion 23 of 323.0/ 3.0 PointsContraction of a skeletal muscle that results from a single stimulus is called a ________.A. twitchB. contraction phaseC. tetanusD. motor unit
Feedback: Correct!Question 24 of 323.0/ 3.0 Points
In the lab, a researcher finds that the threshold stimulus to induce an action potential in a musclefiber’s sarcolemma was 3.0 volts. Which of the following would result in muscle tension?
Feedback: Correct!Question 25 of 323.0/ 3.0 PointsWhat is the minimum voltage needed to generate muscle contraction?
D. threshold voltageFeedback: Correct!Question 26 of 323.0/ 3.0 PointsWhich of the following describes the relaxation phase?
