Question 1

Which collagen type makes up most of healthy tendons and ligaments and provides tensile strength?

Accepted Answer

Type I

Answer

Type I collagen forms thick, strong fibers that resist tensile loads in tendons and ligaments.

Question 2

During the proliferative phase of soft tissue healing, the early, weaker collagen laid down is mostly:

Accepted Answer

Type III

Answer

Fibroblasts first deposit Type III collagen, which is gradually replaced by Type I during remodeling.

Question 3

The principle that soft tissue remodels according to the mechanical demands placed on it is known as:

Accepted Answer

Davis's law

Answer

Davis's law describes soft tissue adapting to imposed stress, while Wolff's law applies to bone.

Question 4

A tendon slowly lengthens under a constant, sustained load. This viscoelastic property is called:

Accepted Answer

Creep

Answer

Creep is gradual deformation over time under a constant load.

Question 5

On a stress-strain curve, loading tissue into the plastic region results in:

Accepted Answer

Permanent deformation with microfailure

Answer

Beyond the elastic limit, collagen crosslinks fail and the tissue does not return to its original length.
