b. morula, a small, tightly packed bunch of cells that is the result of cleavage. A hollow ball of cells is formed after, called the blasocyst. The gastrula still comes later,when cells begin to push at the primitive streak.

The brain and spinal cord are among the first organs to develop in a pregnancy, forming within the first few weeks after conception. These structures are vital for the proper growth and development of the embryo.

∙ 13y agoThe cells that are madly dividing in the days after conception will eventually split off to form the placenta, umbilical cord and the baby. By 25 days there is a tiny heart starting to beat, a rudimentary circulatory system and a neural tube that will develop into the CNS, including the brain and spinal cord.
Spina Bifida occurs in this very early stage - the neural tube fails to close completely - leaving the brain and or the spine open to damage.
