In this article, we calibrate developmental series of the broad‐snouted caiman, Caiman latirostris , against an established series for Alligator mississippiensis . 2020-10-29 · In this article we describe the embryological development of the heart. For thousands of years, the heart has been considered one of the most important organs in the body. Aristotle even believed that other organs existed just to cool it, including the brain and lungs (which we now know perform their own vital functions).

The normal period of gestation (pregnancy) is about nine months or 40 weeks. Nervous System Development in the Human Embryo (a) At 18 days after conception the embryo consists of 3 layers of cells: endoderm, mesoderm, and ectoderm. Thickening of the ectoderm leads to the development of the neural plate. (b) The neural groove begins to develop at 20 days. 2020-01-08 · An embryo of an organism is the fertilized egg as it goes through the processes of development that is specific to that species. When looking at how the animal develops from an embryo to an adult, you can compare the processes with those of other organisms to help determine evolutionary similarities.

The embryological development of the cerebral vasculature is very complex. Historical and also more recent studies based on human embryos, comparative anatomy and cerebral angiographies allowed us to better understand this vasculature development. The knowledge and understanding of such embryological development are important for physicians interested in neurovascular pathologies. Indeed, all Development of the adrenal medulla Trunk neural crest cells migrate into the center of the adrenal glands and develop into the chromaffin cells of the adrenal medulla. These cells are essentially postganglionic sympathetic neurons that release epinephrine or norepinephrine directly into the bloodstream as opposed to innervating a target organ.
