Neurulation is the formation of the neural tube from ectodermal cells during embryonic development. The neural tube later develops into the individual structures of the central nervous system. In neurulation disorders, the formation of the neural tube is defective, which can result in various malformations of the nervous system. What is neurulation? Neurulation, in the … Neurulation: Function, Tasks, Role & Diseases
Since the end of the 20th century, it has been known that the brain is capable of forming new cells even in adulthood through neurogenesis. Accordingly, neurogenesis is the formation of new neurons from progenitor and stem cells, which occurs both during embryogenesis and in the adult nervous system. What is neurogenesis? Neurogenesis is the … Neurogenesis: Function, Tasks, Role & Diseases
Organogenesis refers to the process of development of organ systems during embryogenesis. In humans, organogenesis begins during the first to second week of embryo and ends around the 61st day of pregnancy with the onset of fetogenesis. What is organogenesis Organogenesis refers to the process of developing organ systems during embryogenesis. In humans, organogenesis begins … Organogenesis: Function, Tasks, Role & Diseases
Embryogenesis involution is a basic movement of gastrulation. In addition, in involution in medicine often stands for the natural regression of a tissue with age. In pathophysiology, pathological regression of abilities and tissues is associated with this term. What is involution? In medicine, the term involution is used to describe a degenerative process in which … Involution: Function, Tasks, Role & Diseases
Ingression or immigration is a cell movement of gastrulation and thus constitutes an embryonic developmental step. In this process, cells of the prospective endoderm, i.e., those of the outer cotyledon, migrate into the blastula. Errors in cell movements during the early development of the cotyledons lead to miscarriage in most cases. What is ingression? Ingression … Ingression: Function, Tasks, Role & Diseases
Differentiation in biology characterizes the transformation from a poorly differentiated to a highly differentiated state. This process has particular importance during the development of the fertilized egg into a complete organism. Disturbances in the differentiation process can lead to serious diseases such as cancer or malformations. What is differentiation? Biological differentiation is about the specialization … Differentiation: Function, Tasks, Role & Diseases
Embryogenetic delamination corresponds to a process in which the cells of the blastula cut off the cells of the future endoderm into the blastocoel. Delamination is a step in gastrulation and is related to cotyledon formation. Delamination in the context of embryogenesis must be distinguished from delamination in the context of pathophysiology. What is delamination? … Delamination: Function, Tasks, Role & Diseases
Epiboly is a cell movement of gastrulation that corresponds in principle to invagination. In this process, the prospective endoderm is overgrown by the prospective ectoderm. Disturbances of epiboly occur, for example, when there is a loss of function of the molecule fibronectin and can cause miscarriage. What is epiboly? Epiboly is a cell movement of … Epiboly: Function, Tasks, Role & Diseases
The term ectoderm, which is derived from the Greek ektos, meaning outside, and derma, meaning skin, refers to the first upper cotyledon. It forms the nervous system during development, as well as the skin in humans and also in animals. What is the ectoderm? During the so-called gastrulation, which is an essential part of development, … Ectoderm: Structure, Function & Diseases
Ectodermal dysplasia is a group of genetic malformations of tissues and body parts that arise from the ectoderm. The common abbreviation of ectodermal dysplasia is ED. The term stands for a variety of diseases and pathological disorders, especially of the nails, hair, skin, sweat glands and teeth. Ectodermal dysplasia occurs, for example, in Ellis-van Creveld … Ectodermal Dysplasia: Causes, Symptoms & Treatment
Gastrulation is a stage of early embryonic development. During this stage, the three germ layers of the embryo, the endoderm, mesoderm, and ectoderm, are formed. Gastrulation disorders cause severe malformations that result in death in most cases. What is gastrulation? Gastrulation is a stage of early embryonic development. During embryogenesis, the human embryo forms its … Gastrulation: Function, Tasks, Role & Diseases
The neural tube is an embryonic anlage in early pregnancy that is found not only in humans but in all vertebrates. As development proceeds, it gives rise to the central nervous system, the spinal cord, and the brain. If there are disturbances in the formation and further development of the neural tube, severe malformations are … Neural Tube: Structure, Function & Diseases
