With this post, we continue our biweekly series on medications used to treat bipolar disorder and related symptoms. This week, we focus the spotlight on Tegretol (carbamazepine) â an anti-seizure medication that has been found useful in treating bipolar disorder. Useful in treating acute mania and mixed states particularly when a person doesnât respond well to or tolerate lithium or valproate (Depakote).
Cleavage-Blastula Structure. The blastula is a hollow ball of cells organized into an epithelial monolayer. Midway through the blastula stage, the embryo secretes hatching enzyme, which results in proteolytic degradation of the fertilization envelope.leavage-Blastula Structure.

During the process of embryogenesis, blastula formation is followed by the gastrula, thus both represents a different stage of embryo formation. The blastula and gastrula are formed through different processes. The blastula is formed through blastulation, while the gastrula is formed through gastrulation. The blastula and gastrula are formed through different speeds of mitotic divisions. The blastula is formed through rapid mitotic divisions of the zygote, while slow mitotic divisions of the blastula results in the gastrula. In the process of blastula formation, the cells do not move. However, during the gastrula formation process, the cell masses move through morphogenetic movements. Unlike the blastula, there are three distinct germ layers that are present in the gastrula.
