Developmental morphological and histological studies on structures of the human fetal shoulder joint.
In the present work, morphological changes in the interior structures of the developing human shoulder joint were studied at different prenatal ages (9, 12, 16, 23 and 40 weeks) and were compared with the same structures in the adult joint. It was found that the shoulder joint had gone through important developmental changes during the 12th week of the prenatal life and it is assumed that genet...

Previous reports have shown the foetal disc to be avascular, with a high content of organized collagen fibres and a lesser content of elastic fibres. In this study, ...
متن کاملThe pancreaticoduodenal arteries in human foetal development.
Knowledge of the course of the pancreaticoduodenal arteries is of great importance in pancreatic surgery. Lack of care in the preparation of these vessels may lead to ischaemia or necrosis of the duodenum, the first loop of the jejunum, the head of the pancreas and even the liver, bile ducts and transverse colon. In such events, the surgeon would need to diagnose the course of the vessels and t...
