In summary, the conversation discusses a picture of a developing alligator embryo that is fluorescently labeled and shows various stages of development. The key to the figure highlights the conserved parts among all vertebrates and their embryological layout. The conversation also mentions the differences in invertebrate embryos and the importance of studying vertebrates in medical research.

Recently I ran across this very nice picture of a developing alligator embryo (lower jaw yet to grow out).

It is fluorescently labeled: orange muscle cells, green neural cells and some skin, and bluish on other tissues, and shows a lot of interesting development going on. There are also some green cells that could be neural crest cells.

For the developmentally unaware, I have made a key to this figure:

All of these embryo parts are conserved among and found in all vertebrates. They all share the same embryological layout, which generates similar but different adult forms. You can see all these parts (in distorted form) in fish, frog, bird, whale, and human embryos.
Here is a wikipedia article on the cranial nerves, some of which I have labeled.
Here is one on the pharyngeal arches (same as branchial arches) and their derivatives.

Invertebrate embryos are vastly different and generate body plans that are vastly different, which is why so much medical research (focused on particular body parts) is done on vertebrates.

Related to Very Nice Alligator Embryo Picture

What is the significance of the "Very Nice Alligator Embryo Picture" in science?

The "Very Nice Alligator Embryo Picture" is significant in science because it provides valuable insight into the development and growth of alligator embryos. It allows scientists to study the anatomical structures and developmental stages of alligator embryos in detail, which can help in understanding the evolution and adaptation of these animals.

How was the "Very Nice Alligator Embryo Picture" obtained?

The "Very Nice Alligator Embryo Picture" was obtained through a process called histological sectioning. This involves taking thin slices of tissue from the alligator embryo and staining them with dyes to enhance the visibility of different structures. The slices are then examined under a microscope and photographed to create the image.

What can we learn from the "Very Nice Alligator Embryo Picture"?

The "Very Nice Alligator Embryo Picture" can teach us about the anatomy and development of alligator embryos, including the growth of different organs and tissues. It can also provide insights into the evolutionary relationships between alligators and other species, as well as how their development is influenced by their environment.

Is the "Very Nice Alligator Embryo Picture" a real photo or an illustration?

The "Very Nice Alligator Embryo Picture" is a real photo. It is a microscopic image of an actual alligator embryo that has been magnified and enhanced for better visibility. It is not an illustration or a computer-generated image.

Can the "Very Nice Alligator Embryo Picture" be used for research purposes?

Yes, the "Very Nice Alligator Embryo Picture" is a valuable tool for research in the field of developmental biology and evolutionary studies. It can be used to compare and analyze different stages of alligator embryo development and can provide important insights into the development of other species as well.
