The paratesticular region is a relatively small anatomical compartment containing a disproportionately large number of anatomic structures. In addition to the testicular collecting system there are mesothelial and mesenchymal components representing extensions of the abdominal cavity and retroperitoneum. The epithelial, mesothelial, and connective tissue elements give rise to a wide variety of ...
متن کاملHypospadias. Anatomy, Embryology, and Reconstructive Techniques
Hypospadias is one of the most common congenital anomalies that can be treated with surgical reconstruction. The etiology in the majority of cases of hypospadias remains elusive. Androgens are clearly critical for penile development; however, defects in androgen metabolism and/or the androgen receptor explain only a small subset of patients with hypospadias. This paper reviews the present strat...

Polypterus,a model animal for studying tetrapod evolution The evolutionary transition from aquatic vertebrates to terrestrial tetrapods occurred around 370 million years ago in the late Devonian period. What changes in genome function caused such evolution and led to the development of new organ remains uncertain. We have been investigating the evolution of the tetrapod body plan using a primit...
متن کاملNasal, septal, and turbinate anatomy and embryology.
This article discusses the development and anatomy of the nasal septum and structures of the lateral nasal wall. Emphasis is placed on anatomic variations associated with surgically correctable nasal obstruction. Common variations, such as deviated nasal septum, inferior turbinate hypertrophy, paradoxic middle turbinate, and concha bullosa, are discussed. Rare developmental causes of nasal obst...

In adult terrestrial heterothermic vertebrates, spontaneous or experimentally induced plasticity of the brain is widely demonstrated. This phenomenon is more pronounced in Amphibians than in lacertilians, the most investigated among the Reptiles. In the lizard it has been observed that the summer photoperiod and temperature exert a positive influence on the proliferative activity of cerebral pu...
