Different races have differences in their joint mobility, which may reflect differences in the structure of the collagen proteins.

The middle layer of the pars tensa is strengthened by fibres of collagen protein.

Usually, the burning heat of cremation shrinks the collagen protein at the center of bones, causing them to warp and fracture.

In 2011, collagen protein was recovered from a Prognathodon humerus dated to the Cretaceous.

Its base layer consists of fibroblasts, whose tendrils bind together the skin's "skeleton," gel-like strands of collagen protein.

The upper chambers (atria) and lower (ventricles) are electrically divided by the properties of collagen proteins within the rings.

Spongin, a modified type of collagen protein, forms the fibrous skeleton of most organisms among the phylum Porifera, the sponges.

There are many different types of collagen protein in each of the body's tissues.

Bath sponges can be defined as any sponge species possessing only spongin fibers - which are springy fibres made from collagen protein.
