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.

A morula is distinct from a blastocyst in that a morula (3-4 days post fertilization) is an 8 cell mass in a spherical shape whereas a blastocyst (4-5 days post fertilization) has a cavity inside the zona pellucida along with an inner cell mass.he morula is produced by a series of cleavage divisions of the early embryo, starting with the single-celled zygote. Once the embryo has divided into 16 cells, it begins to resemble a mulberry, hence the name morula (Latin, morus: mulberry).
