During the so-called hatching of embryogenesis, the blastocyst hatches from the vitreous membrane, by which it is enclosed until about the fifth day after conception. This first birth of the offspring is the prerequisite for implantation in the uterus. In in vitro fertilization, hatching is partially induced externally by laser. What is hatching? During the … Hatching: Function, Tasks, Role & Diseases
Juvenile stage refers to the stage of a living being after birth and before sexual maturity. After that, they are considered adults (adolescence); before that, they are in the embryonic stage. In humans, the juvenile phase goes from infancy to early adolescence (pubescence). What is the juvenile stage? The juvenile phase refers to the phase … Juvenile Phase: Function, Tasks, Role & Diseases
Prostacyclin is a tissue hormone that belongs to the series 2 prostaglandins. The hormone is produced mainly in vascular endothelial cells and smooth muscle cells from arachidonic acid. It has a local vasodilatory effect, increases pain by sensitizing nociceptors, induces fever, and greatly inhibits platelet aggregation. What is prostacyclin? Prostacyclin, also known as prostaglandin l2 … Prostacyclin: Function & Diseases
The process of formation and formation of teeth is called odontogenesis. More precisely, it is understood as the period in which the first attachments of the milk teeth are formed and the eruption of the teeth of the permanent dentition occurs, along with the development of the dental ridge, the formation of enamel, dental crown, … Odontogenesis: Function, Tasks, Role & Diseases
Hemoglobin is one of the compounds in the body that provides oxygen transport. It is found in red blood cells. Red blood cells have a lifespan of approximately 120 days. After that, the red blood cells are broken down in the body, and with them the hemoglobin they contain. This hemoglobin breakdown takes place first … Hemoglobin Degradation: Function, Tasks, Role & Diseases
Bonnet-Dechaume-Blanc syndrome is the name given to a very rare condition that is already congenital. The condition is noticeable by arteriovenous malformations in the retinal blood vessels and facial changes. What is Bonnet-Dechaume-Blanc syndrome? In the medical community, Bonnet-Dechaume-Blanc syndrome is also known as congenital retinocephalofacial vascular malformation syndrome (CRC syndrome) or Wyburn-Mason syndrome. Among … Bonnet-Dechaume-Blanc Syndrome: Causes, Symptoms & Treatment
The gonads are the gonads of humans that perform both exocrine and endocrine functions and play a major role in reproduction. In addition to germ cells, the gonads produce sex hormones that regulate reproduction. Diseases of the gonads often manifest as overproduction or underproduction. What is the gonad? The gonads are the male and female … Gonad: 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
Transdifferentiation involves metamorphosis. The differentiated cells of a particular cotyledon are transformed into the cells of another cotyledon by processes such as histone deacetylation and methylation. Defective processes of transdifferentiation underlie many diseases, such as Barrett’s esthrophagus. What is transdifferentiation? Scientists associate transdifferentiation ability primarily with human stem cells. Embryonic development occurs on the basis … Transdifferentiation: Function, Tasks, Role & Diseases
Furrowing of the zygote is a cell division in early embryogenesis. It follows fertilization and is part of preembyonic development. Errors in furrow division are associated with gene mutations such as trisomies or parental disomies. What is furrowing? Furchung of the zygote is a cell division in early embryogenesis. It follows fertilization and is part … Furrow: Function, Tasks, Role & Diseases
