Otic vesicle the lateral side will be paraxial mesoderm. Neural crest cells will migrate rostral and caudal to the placode. The general sequence in formation of the otic vesicle is relatively conserved across vertebrates, although there is much variation in timing and stages. Patterning during morphogenesis into the distinctive inner ear structures is determined by homeobox transcription factors including PAX2, DLX5 and DLX6, with the former specifying for ventral otic vesicle derived auditory structures and the latter two specifying for dorsal vestibular structures. The otic vesicle is derived from the cranial placode. The early otic vesicle is characterized as having broad competence
Body donation Body donation Body donation, anatomical donation, or body bequest is the donation of a whole body after death for research and education. Donated bodies are mostly used for medical education and research. They are used for gross anatomy, surgical anatomy and for furthering medical education. For years, only medical schools accepted bodies for donation, but now private programs also accept donors. Depending on the program's need for body donation, some programs accept donors with different specifications. Body donation is important for understanding the human body and for making advancements in science. There is usually no cost to donate a body
