Histology Look-a-like #153
33 Day Chick Embryo v A Rocket
5…If you think embryology is the worst, horrible and incredibly boring. Then this image proves you wrong because quite clearly it is an absolute blast.
4…In this growing chick you can see the regions of the developing brain (prosencephalon, mesencephalon rhombencephalon) that appear to be forming the rocket itself.
3…The plume of flames is formed by the developing neural tube (primitive spinal cord) and somites (balls of mesenchymal cells that will differentiate to form muscle, bone, dermis and connective tissue).
2…Notice that the end of this plume terminates in a cone of fire. It has this appearance because the neural groove is still present in this region. The neural grove is a furrow in the ectoderm the high sides of which will eventually meet in the midline to form the hollow neural tube.
1…If you are having trouble figuring out the anatomy. This interactive 33hr chick helps demonstrate the embryological structures in serial sections.
