Diktat is a German word that means "dictation" or "dictatorship." It is often used to refer to the harsh terms imposed on a defeated country by the victors in a war. In the context of Germany, the term diktat is most commonly associated with the Treaty of Versailles, which was signed at the end of World War I in 1919.
The Treaty of Versailles was a peace treaty between the Allied Powers (led by France, the United Kingdom, and the United States) and Germany. It was meant to bring an end to the war and to establish the terms under which the defeated Germany would be forced to pay reparations to the Allied Powers. The treaty also imposed severe limitations on Germany's military and territorial expansion.
Many Germans viewed the Treaty of Versailles as a diktat, or dictate, because they felt that the terms were imposed on them by the victorious Allies without any input from the German government or people. The treaty was seen as extremely harsh and punitive, and many Germans felt that their country had been humiliated and treated unfairly.
The resentment and anger that many Germans felt towards the Treaty of Versailles played a significant role in the rise of Adolf Hitler and the Nazi Party in the 1920s and 1930s. Hitler and the Nazis promised to restore Germany's honor and power, and they used the treaty as a rallying cry to mobilize support for their cause. Hitler came to power in 1933, and he quickly set about tearing up the Treaty of Versailles and rebuilding the German military. This ultimately led to World War II, which ended with the defeat of Germany and the imposition of another set of harsh terms in the form of the Potsdam Agreement.
In conclusion, the term diktat is closely associated with the Treaty of Versailles and its impact on Germany following World War I. Many Germans saw the treaty as a dictate imposed on them by the victorious Allies, and the resentment and anger that it generated played a significant role in the rise of the Nazi Party and the outbreak of World War II.
Embryonic Development Cleavage and Egg Types Multiple Choice Questions PDF
Micromeres divide at faster rate while the macromeres at slower rate. When implantation succeeds and the blastocyst adheres to the endometrium, the superficial cells of the trophoblast fuse with each other, forming the syncytiotrophoblast, a multinucleated body that digests endometrial cells to firmly secure the blastocyst to the uterine wall. The blastula contains a cavity named blastocoel and its outer covering is designated as blastoderm. Cleavage in Chick Embryo Cleavage in a chick embryo is a complete ten stage cycle development process to form an egg. Development of the Placenta During the first several weeks of development, the cells of the endometrium—referred to as decidual cells—nourish the nascent embryo. Meroblastic cleavage may be of two types.
Cleavage: Meaning, Planes and Types
Cleavage is holoblastic and rotational. It gradually extends towards the vegetal pole of the egg. A folate-deficient environment increases the risk of a neural tube defect, such as spina bidifa, in the newborn. Laws of cleavage Apparently there are several cleavage patterns. Floating within the amniotic fluid, the embryo—and later, the fetus—is protected from trauma and rapid temperature changes. This disc remains firmly connected with the underlying yolk.
Types of animal eggs and their cleavage
Paddle-shaped hands and feet develop fingers and toes by the process of apoptosis programmed cell death , which causes the tissues between the fingers to disintegrate. The third cleavage is horizontal but slightly above the equator. The placenta connects to the conceptus via the umbilical cord, which carries deoxygenated blood and wastes from the fetus through two umbilical arteries; nutrients and oxygen are carried from the mother to the fetus through the single umbilical vein. This ability varies greatly among living things. Such a cleavage may be either equal or unequal. However, there is no increase in mass, but the zygote undergoes division to multiple cells of a similar kind. During its journey to the uterus, the zygote undergoes five or six rapid mitotic cell divisions.
Cleavage and types
Cells migrate toward and through the primitive streak and then move laterally to create two new layers of cells. When an egg is fertilised, it undergoes various divisions. Gradually 40—50 hours after fertilization , a four-cell stage occurs, in which two blastomeres are larger and two are smaller. Meanwhile, fetal mesenchymal cells derived from the mesoderm fill the villi and differentiate into blood vessels, including the three umbilical blood vessels that connect the embryo to the developing placenta Figure 28. But is the embryo fully patterned in the fertilized egg? During the fourth and fifth weeks, the anterior neural tube dilates and subdivides to form vesicles that will become the brain structures. It can be subdivided into distinct gestational periods. The first cleavage of frog's egg was observed by Swammerdamin 1738.
Cleavage
We Stand Out because We successfully provide students with intensive courses by India's top faculties and personal mentors. Biological Physics of the Developing Embryo. The fourth cleavage is meridional which involves all the eight cells resulting in the formaÂtion of eight micromeres and eight macroÂmeres. Langman's medical embryology 11thed. Meroblastic The cleavage furrow in macrolecithal egg does not divide the zygote completely and is restricted to only animal pole. If the embryo implants in the inferior portion of the uterus, the placenta can potentially grow over the opening of the cervix, a condition call placenta previa. Upon reaching the uterus, the conceptus has become a tightly packed sphere of cells called the morula, which then forms into a blastocyst consisting of an inner cell mass within a fluid-filled cavity surrounded by trophoblasts.
28.2 Embryonic Development
Equatorial plane of cleavage: This type of cleavage plane divides the egg halfway between the animal and vegetal poles and the line of division runs at right angle to the median axis. Following implantation, embryonic cells undergo gastrulation, in which they differentiate and separate into an embryonic disc and establish three primary germ layers the endoderm, mesoderm, and ectoderm. However, all cleav-ages follow a common procedure. What Makes Us Different Physics Wallah strives to develop a comprehensive pedagogical structure for students, where they get a state-of-the-art learning experience with study material and resources. The trophoÂblastic cells overlying the embryonic knob is called cells of Rauber.
