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 term anencephaly refers to a severe malformation of the embryo that occurs early in pregnancy. Due to an unclosed skull and missing parts of the brain, the life expectancy of newborns suffering from anencephaly is only a few hours or days. What is anencephaly? A reliable diagnosis of suspected anencephaly is made using a … Anencephaly: Causes, Symptoms & Treatment
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
Tetrahydrofolic acid plays an important role in the transfer of carbon as coenzyme F in the organism. It is synthesized from folic acid (vitamin B9). Deficiency of THF triggers, among other things, macrocytic anemia, the form triggered by vitamin B12 deficiency being called pernicious anemia. What is tetrahydrofolic acid? Tetrahydrofolic acid functions as an important … Tetrahydrofolic Acid: Function & Diseases
Alpha-1-fetoprotein (AFP) is formed mainly in embryonic tissues, where it serves as a transport protein. After birth, very little AFP is formed. Elevated serum or blood levels in children and adults indicate tumors, among other things. What is alpha-1 fetoprotein? Alpha-1 fetoprotein is a protein that is produced in the entodermal tissue during embryogenesis. The … Alpha-1 Fetoprotein: Function & 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
If a neural tube defect is detected during pregnancy in an ultrasound examination, it comes as a great shock to the parents-to-be. Depending on the severity of this malformation, the baby may not be able to survive or may be born with disabilities, some of them severe. In Germany, the risk of giving birth to … Neural Tube Defect: Causes, Symptoms & Treatment
How is cell development defined? What are its functions, what are its tasks in embryogenesis? What diseases can occur that affect cell development? All of this is discussed below. What is cell development? After fertilization occurs, the two half sets of chromosomes from the sperm and egg attach to each other and cell division begins. … Cell Development: Function, Tasks, Role & Diseases
The term neural tube defect refers to malformations of the central nervous system that result from inadequate closure of the neural tube. This is the first (tubular) attachment of the nervous system in the embryo, from which the brain and spinal cord develop. Towards the end of the first week of pregnancy, the neural tube … What is a Neural Tube Defect?
The central canal, or canalis centralis, is a tubular structure that runs through the spinal cord and extends into the medulla oblongata. Errors in embryonic development can result in neural tube defects; one example is anencephaly. In addition, tumors can form from the ependyma of the central canal. What is the central canal? The central … Central Canal: Structure, Function & Diseases
