Which of the following is the ratio of the stress caused by an applied strain in tissues?

Stiffness

Which of the following correctly describes the effect when a contractile element in muscle is lengthened beyond resting (ideal) length?

there will be less potential to create a force

Which of the following is true for total length tension curve of a typical muscle?

Passive tension is the main contributor to the total force when a muscle is maximally lengthened beyond resting length

Which of the following would result if there was tissue damage (loss of structure or function) to the articular cartilage of a joint?

There would be a loss of ability to reduce friction

Which of the following best describes why the force produced by an isometric contraction will change depending on the joint angle position?

There is a change in the length of the muscle

Which of the following best describes the tissue response of creep?

Tissue length changes while force remains constant

Which of the following is correct based on the stress-strain curve for tissues?

Strain (x-axis) refers to the change in tissue length
