Chicken: 22-28 h In the stage from 22 hours on, the somites formed in the mesoderm at the left and right side of the neural walls become visible. After 24 hours 4 to 5 segmented paired blocks can be discerned. The Virtual Chicken project was funded by a USDA Higher Education Challenge Grant. Virtual chicken provides teaching and learning resources that include a video showing the formation of an egg in a hen, slide presentations and hands on experiments for educators.

Chicken Embryos. The chick or baby chicken is not only a favorite as a reminder of spring and as a live Easter gift for children in the United States, but is also well studied by embryologists, toxicologists, and histologists. Because of their relatively low cost, abundance, and year-round supply, chicken embryos make ideal laboratory organisms. The embryos were treated at either 48, 72, or 96 hours incubation. On day 9, live embryos were recovered and examined for external malformations after staging and weighing. Treatment with 400 and 1,100 micrograms caffeine at 48 hours incubation resulted in a significantly high incidence of abnormal embryos, compared to the controls.Chicken Embryos.

24 Hour Chick embryo. THE ANATOMICAL FEATURES OF 32-HOUR CHICK EMBRYO : 1. Three major divisions of brain i.e. Procencephalon, Mesencephalon and Rhombencephalon are distinguishable. 2. Notochord is distinct. 3. There are 10 pairs of somites and elongated foregut is present. Features. First somite becomes dispersed (and not included in count). This was a 72 hour embryo. We made a drawing of the embryo and then labeled many of its structures. This lab was helpful in seeing how an embryo looks like being a little bit older than the ones w we looked at in the previous lab and seeing how the heart works within it.Torsion: The 24 hours chick embryo is flat. Its ventral surface is in contact with yolk. As the development proceeds the anterior end of embryo is turns towards right and hence the anterior part of embryo comes to lie on the left side of yolk. This twisting is called torsion. At the end of 48 hours chick twisting will reach the cervical flexure.72 hr Chick

The allantois is an extra-embryonic membrane that begins to grow from the hindgut of the chick embryo around 66 hours.

Because of their relatively low cost, abundance, and year-round supply, chicken embryos make ideal laboratory organisms. The fine structure of developing cartilage is described in the area of the future vertebral bodies in the cervical region of chick embryos. Incubation ages range from 36 hours, when the sclerotome of the somite begins to break up, to the thirteenth day. In the 36‐ to 72‐hour interval cells of the sclerotome become free and assume stellate form.The winning video (above) uses an injection of ink into a 72-hour-old chick embryo to illustrate the blood system.
