Read about herniated disc (disc herniation of the spine) symptoms and treatment options, including exercises and surgery. The germinal vesicle, indicated by the arrow, shows this egg to be in prophase i of the first meiotic division. The embryonic disc located near the center of the elongating trophectoderm continues to develop and signaling such as axon guidance, wnt signaling, and p53 signaling pathways guide the conceptus.

Find out when surgery is an option to treat a herniated disk, and which procedures might be right for you.

In the embryo stage around 20 hours after fertilization, the head fold is visible as a half. A disklike spot in a fertilized ovum in which the first traces of the embryo are visible 2. Furthermore, avian embryos demonstrate discoidal meroblastic cleavage with a large amount of yolk and a small germinal disc 1,2, which hinders monitoring early embryo development. Bone morphogenetic proteins(bmp)play an important role.
