30. "FORMATION DU SQUELETTE DES MEMBRES 



CHEZ L'HOMME" 

 1962 

 by G. Olivier Vigot Freres 



231 pp., 123 figs. Paris 



In this monograph the development of the bones and girdles in the human 

 embryo and foetus is studied. The joints are not included. The study is based 

 on reconstruction of microscopic sections of embryonic stages and on dissection 

 in the foetal phase. The primary aim of the author is to give a morphological 

 description of the development of the different bones. A study of the causal 

 relations in this development is not included. On the other hand, some attention 

 is given to phylogenetic aspects. In every chapter a special bone is discussed 

 extensively. Chapters are successively devoted to the clavicle, the scapula, the 

 humerus, the bones of the fore-arm, the hand, the hip-bone, the femur, the 

 bones of the leg, the foot. In every chapter the material is, as a rule, treated 

 according to the following subdivision: time of appearance; place and orien- 

 tation; embryonic form; histology; foetal and infantile morphology; ossifi- 

 cation. In a final chapter a biometrical study of the growth of the same bones 

 is presented. 



The book is richly illustrated with simple but very clear line drawings and 

 a few photographs. There are extensive summaries in English, Spanish and 

 German. The bibliography covers 8 pages. The book is concluded by a short 

 subject index.
