In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the ...

Scientists have officially grown a notochord—the tissues that act as the “GPS for the developing embryo” by guiding the formation of the spine and nervous system. Previous attempts to create ...

Figure 2: In this 5-day-old chicken embryo imaged with an Olympus SZX12 stereo microscope equipped with fluorescence optics, GFP can easily be detected in the spinal cord. It is also important to ...

The ideal fetal position for birth is head down, spine parallel to the pregnant person's spine, face toward the back of the pregnant person's body with the chin tucked and arms folded across the ...

For the first eight weeks, the developing baby is called an embryo. It looks like a tadpole. At about three weeks, the neural tube, which becomes the brain and spinal cord, is forming. At about ...

It also plays an important role in the proper closure of the neural tube—the part of an embryo where the brain and spinal cord develop—and in the normal development of major heart vessels.
