Description
Chicken embryo. Light micrograph of the embryo of a chicken (Gallus domestica), after 60 hours of development, surrounded by the amniotic membrane and yolk blood vessels. At left, the head area includes the swollen anterior bulbous forebrain (prosencephalon), and the eye's lens and optic cup (deep purple). The brain continues as the mid and hind-brain which shows the auditory vesicle (oval reddish purple) and then the neural tube and notocord running to to the end of the body (right). The neural tube has 31 somites (muscle blocks) along either side. The U-shaped heart is in the lighter pink area at right of the head. Magnification: x14 when printed at 10 centimetres across.
