F. Neurulation

Explanation:

The normal path for human embryonic development is as follows:

Gametogenesis

• refers to the production of gametes or sex cells
• production of sperm in males
• production of oocyte in females

Ovulation

• occurs only in females
• a tertiary follicle raptures to release an oocyte into the pelvic cavity
• the oocyte is transported into the uterine tube by contact with the fimbriae and by the ciliary movement of the cells lining the uterine tube

Fertilization

• fertilization usually occurs at the ampulla region of the uterine tube in females
• fertilization is the fusion of the genetic material carried by the sperm and oocyte which results to an zygote, a single diploid cell

Cleavage

• refers to the rapid cell division of a zygote through mitosis without significant overall growth
• the mitotic division produces two cells which will continue dividing to become four cells, then into eight cells until it forms a blastula

Implantation

• refers to the event at which the blastocyst adheres to the wall of the uterus and starts receiving oxygen and nutrients from the mother

Gastrulation

• marked by the appearance of the primitive streak
• at this stage, the two-layer embryo is rearranged into three layers and gives it a distinct head-tail and front-back orientation
• the three germ layers to form in gastrulation are ectoderm, mesoderm, and endoderm

Neurulation

• during neurulation, the epithelial and neural tissue rise develops from the ectoderm
• also referred to as the transformation of the neural tube from the neural plate
