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
The Greek “genesis” means “emergence” and is used as a medical term for the emergence of diseases as well as for physiological processes of new formation. In this context, embryogenesis, which describes the genesis of human life, plays a particularly important role. What is genesis? The Greek “genesis” means “origin.” In this context, embryogenesis plays … Genesis: 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
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
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
Embryonic head development is the term used to summarize skull development, the differentiation of the pharyngeal arch anlagen, and the development of the craniofacial system. Cranial development primarily forms the bony skull base, whereas organs form from the pharyngeal arches. Developmental abnormalities cause dysplasias (visible malformations). What is embryonic head development Embryonic head development is … Embryonic Head Development: Function, Tasks, Role & Diseases
The endoderm is the inner cotyledon of the blastocyte. Various organs develop from it by differentiation and determination, such as the liver. If this embryogenetic development is disturbed, organ malformations may occur. What is the endoderm? The human embryo develops from the so-called blastocyte. During gastrulation, the blastocyte gives rise to three different cotyledons: the … Entoderm: Structure, Function & Diseases
A transdetermination in biology represents the reprogramming of a differentiated somatic cell. In general, the process of differentiation of somatic cells from the fertilized egg to the fully formed organism is irreversible. However, under certain conditions, a cell determined in its differentiation can be reprogrammed. What is transdetermination? In general, the process of differentiation of … Transdetermination: Function, Tasks, Role & Diseases
