Tendon - Ossified Tendons

Ossified Tendons

In some organisms, notable ones being birds and ornithischian dinosaurs, portions of the tendon can become ossified. In this process, osteocytes inflitrate the tendon and lay down bone as they would in sesamoid bone such as the patella. In birds, tendon ossification primarily occurs in the hindlimb, while in ornithischian dinosaurs, ossified axial muscle tendons form a latticework along the neural and haemal spines on the tail, presumably for support.

Famous quotes containing the word tendons:

    Mountains are to the rest of the body of the earth, what violent muscular action is to the body of man. The muscles and tendons of its anatomy are, in the mountain, brought out with force and convulsive energy, full of expression, passion, and strength.
    John Ruskin (1819–1900)
