Oral Histology and Embryology

Embryology, Anatomy, and Histology

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 ...

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...

Embryology of the human fetal hippocampus: MR imaging, anatomy, and histology.

PURPOSE To identify changes in the embryology of the hippocampus responsible for its adult anatomy. METHODS Ten human fetal specimens ranging from 13 to 24 weeks' gestational age were examined with MR imaging. Dissections and histologic sections of 10 different specimens of similar ages were compared with MR imaging findings. RESULTS At 13 to 14 weeks' gestation, the unfolded hippocampus, o...

[Disciplinar thematic integration in medicine: a proposal from histology and embryology].

This paper intends to clarify a concept with multiple meanings and a complex reality. It starts providing varied histological and embryological examples apt to contribute the stimulation of teacher and student imaginations in favor of a crucial skill, as thematic integration is, into the present and changing curricula in Medicine in particular and Health Sciences in general. In this sense, it o...
