Muscular strength depends on all of the following EXCEPT? Question 9 options: A) Size of motor unit B) Temporal summation C) Fascicle arrangement D) Endurance
Added by Erin L.
Step 1
- Size of motor unit: Larger motor units can generate more force, contributing to muscular strength. - Temporal summation: This refers to the process where repeated muscle contractions increase the force produced, which can contribute to muscular strength. - Show more…

23. Which of the following has the most endurance? (a) a Type I fiber (b) a Type IIa fiber (c) a Type IIb fiber (d) fast twitch fibers (e) glycolytic fibers 24. Which of the following will NOT result in an increase in muscle tension (strength of contraction)? (mark all that apply) (a) Increasing the number of neurons firing (b) Increasing the number of muscle fibers contracting (c) Increasing the number Type I vs Type IIb fibers used (more type I used, less Type IIb used) (d) Increasing intracellular Ca2+ (e) Increasing the stretch of the sarcomere to maximal length 25. Which of the following is the primary reason for the fine control of finger movement? (a) The high endurance of the type I fibers (b) The increased number of small motor units (c) The GPCR controlled muscle fibers (d) The higher strength of the type IIb fibers (e) the increased number of large motor units
