The occurrence of the ossifications in human costal cartilages - radiograph-scan, histological and histochemical study
Rejtarová, Olga ; Slížová, Dáša (advisor) ; Kreuzberg, Boris (referee) ; Stingl, Josef (referee)
The costal cartilages belong to the group of the permanent cartilages, as well as thyroid, tracheal and the articular cartilages. These cartilages ossify incompletly or do not ossify at all. The ossification of the caudal costal and the articular cartilages is considered to be a manifestation of degeneration, although according to the recent studies the ossification of the thyroid, the tracheal and the first rib cartilages is physiological. The costal cartilage ossification begins at a different age but only in a certain percentage of people. The female and the male pattern of ossification is different. Although the etiology and the occurence of ossification in various populations were studied very deeply, even at the microscopic level, still a lot of questions are not ansvered. Due to the heterogeneity and insuficiency of the data in the Czech literature we decided to evaluate the incidence of the costal cartilage ossification in the sample of the Czech population. We decided to verify the presence of the sexual dimorfism of the ossification and describe the development of the ossification changes at the microscopic level for better understanding of the ossification of human costal cartilage. There are two parts of our study. We used radiograms for the radiological part of the study. We studied...
