| | The species of Dendrocincla, which form a clade, show secondary reduction of ossification in some tendons, which may be correlated with increased intraspecific variation and with an expansion of foraging habits and postures to include nonscansorial behaviors. | | | anabatina, a member of a clade characterized by reduced tendon ossification, variation in tendon ossification was markedly greater than in other aspects of the hindlimb muscles, as were occurrences of bilateral variation and the number of individuals exhibiting atypical conditions. | | | Phylogenetic analysis suggests that extensive tendon ossification is a synapomorphy of the woodcreepers. |

| | Using Zucker fatty rats as an animal model, we evaluate the effectiveness of ethane-1-hydroxy-1,1-diphosphonate on ossification of the posterior longitudinal ligament by histopathologically investigating the prodromal, early, and advanced stages of ossification of the spinal ligaments. | | | Radiographic examinations showed that osteoproliferation in vertebral bodies in rats receiving ethane-1-hydroxy-1,1-diphosphonate was generally suppressed compared with controls, whereas histopathological examinations found no clear difference in cartilage cell proliferation in areas affected by enthesitis between the two groups, indicating the absence of calcification or osteo-proliferation in areas affected by enthesitis for the rats receiving ethane-1-hydroxy-1,1-diphosphonate. | | | The results showed that ossification of the spinal ligaments involved excessive cartilage cell proliferation around areas affected by enthesitis; enlargement of the fibrocartilage tissue layer; ligament thickening; calcification of the matrix around the cartilage cells; and ossification of the spinal ligaments through enchondral ossification. |

| | Appendicular Skeleton: Ossification |
| | Most important though is the ability of bone to remodel and to change in structure as the forces on an individual's body change throughout life. | | | Because it grows so easily and quickly without requiring any involved remodeling, cartilage is an excellent material for a template, allowing the "bones" of the embryo to grow at the same rate as the embryo while the slower process of ossification makes them structurally sound for life after the womb. | | | The long bones of the appendicular skeleton are the classic example of endochondral ossification and bone growth mechanisms. |

| | Periosteal bone continues to form (intramembranously) and can be recognized histologically because there is no cartilage erosion. | | | The distinction between endochondral and intramembranous formation rests on whether a cartilage model serves as the precursor of the bone (endochondral ossification) or whether the bone is formed by a simpler method, without the intervention of a cartilage precursor (intramembranous ossification). | | | Endochondral ossification, also, begins with the proliferation and aggregation of mesenchymal cells at the site of the future bone – however the mesenchymal cells differentiate into chondroblasts that, in turn, produce cartilage matrix. |
