MODERN INFORMATION ON THE PANCREATIC STRUCTURES FORMATION IN THE EARLY STAGES OF HUMAN ONTOGENESIS

Abstract

"This organ is nourished by the" purest juices "of the splenic vein," Avicenna wrote of the pancreas. In many cases, it takes the brunt of a sudden change in our diet, overeating, or neglect of overall health. However, if you dramatically increase the amount of food consumed or radically change its nature, it is certainly "revenge" for its unwillingness to change the level of enzyme production. The body is unable to absorb undigested food components and, as a result, develops a chronic deficiency of non-essential nutrients. When there are deficient conditions, such as hypovitaminosis, immunodeficiency, disorders of many body functions are provoked. In conditions of pancreatic insufficiency, the body is unable to absorb undigested food components and therefore experiences a chronic deficiency of essential nutrients. Metabolic disorders in organs and tissues, hypovitaminosis, disorders of body functions develop. The pancreas is a mixed gland, which has exocrine structures that make up 98% of its total mass and secrete digestive enzymes that enter through the excretory ducts into the lumen of the duodenum, and endocrine, consisting of several groups of cells that form islets Langerhans, which produce a number of hormones. The pancreas in the prenatal period of development develops in three stages. Up-during 5-10 weeks (the first stage) there is a bookmark of body, its form and topography is defined. The second stage (11-20 weeks) is characterized by active histogenesis of the gland, the formation of its bloodstream and nervous system. The third stage, which lasts until birth, is the differentiation of pancreatic structures, their quantitative growth, the gland begins to function. The presented work accurately describes the ontogenetic features in the structure of the gastrointestinal tract, namely: the pancreas.
