Neurulation refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube.

Illustration depicting ovulation and fertilization. Human fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the uterine tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development.Scientists discovered the dynamics of human fertilization in the nineteenth century.The process of fertilization involves a sperm fusing with an ovum.The most common sequence begins with ejaculation during copulation, follows with ovulation, and finishes with fertilization.cientists discovered the dynamics of human fertilization in the nineteenth century.
