Facial nerve: embryology and anatomy of its nucleus

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 ...

Facial nerve anatomy in eyelids and periorbit.

PURPOSE To clarify anatomically the facial nerve branches in the eyelids and periorbit. METHODS The facial nerve branches of the left periorbits from 31 Japanese cadavers were dissected under a surgical microscope. RESULTS The temporal, zygomatic, and deep buccal branches assembled posterior to the orbicularis oculi from its temporal or inferior side, and formed a dense plexus. The superfic...

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...
