A Lecturer from the Department of Biology Publishes a Scientific Article on the Embryonic Formation

Scientific Article


The educational assistant at the College of Education for Pure Sciences/Department of biology, Assistant Professor Dr. (Alaa Hussein Mahdi), obtained the acceptance to publish a scientific article tagged (embryonic formation) from the Scientific Articles Committee at the Presidency of Karbala University, after the article fulfilled all publication conditions. (Asst. Prof. Dr. Alaa Hussein Mahdi) stated that the embryo-enesis process is the basis for creating the final shape of adults, and this process does not consist simply of the growth of a preformed miniature embryo in size, but rather it is a huge dynamic process characterized by a large amount of morphogenetic movement Reorganization, the embryo begins as a single cell, the fertilized egg (zygote), which undergoes many repeated divisions (cell division without increasing growth), which leads to a gradual decrease in its size, which is arranged in a pattern that generates the final shape of the embryo. These cells are called blastomers, which Then a mass called the morula is formed, consisting of 16 cells. At this stage, the nucleus consists of a group of centrally located cells whose cells are slow to divide, called the inner cell mass, from which fetal tissues arise, and a group of peripheral cells that form one layer of rapidly dividing cells surrounding the first called the outer cell mass, which is the Trophoblast cells.
