NEET PG DENTAL EXAM

Detailed explanation-1: -Gastrulation leads to the formation of the three germ layers that give rise during further development to the different organs in the animal body. This process is called organogenesis. Organs develop from the germ layers through the process of differentiation.

Detailed explanation-2: -Organogenesis is important for the concurrent development of multiple organs and organ systems. Organs arise from the endoderm, ectoderm, and mesoderm; the three primary germ cell layers are established during gastrulation. Each of these layers is derived from the epiblast. By week eight, organogenesis is complete.

Detailed explanation-3: -These changes are due to alterations in the set of genes expressed in the cells. Eventually, the cells of the embryo are split into three different groups known as germ layers: mesoderm, endoderm, and ectoderm. Each germ layer will, under normal conditions, give rise to its own specific set of tissues and organs.

Detailed explanation-4: -organogenesis, in embryology, the series of organized integrated processes that transforms an amorphous mass of cells into a complete organ in the developing embryo. The cells of an organ-forming region undergo differential development and movement to form an organ primordium, or anlage.
