Question

which of the following statements about skeletal muscle is true? skeletal muscles are not capable of rapid contraction and relaxation. short muscle fibers run at an angle to the longitudinal axis of the muscle. during muscle contraction, skeletal muscle lengthens. skeletal muscles are usually linked to each other by tendons. question 58 the sliding of protein filaments over each other to create movement is called the muscle - stroke theory. true false question 30

Explanation:

1. Skeletal muscles can contract and relax rapidly, so the first option is false.
2. Short muscle fibers run parallel to the longitudinal axis of the muscle in many cases, not at an angle as stated in the second option.
3. During muscle contraction, skeletal muscle shortens, not lengthens, so the third option is incorrect.
4. Skeletal muscles are usually attached to bones by tendons, not to each other.
5. The sliding - filament theory describes the sliding of protein filaments (actin and myosin) over each other to create movement, so the statement in question 58 is true.

Answer:

For the first question: None of the above.
For question 58: True.
