| French physiologist Date of Birth: 12.07.1813 Country: France |
Claude Bernard was a French physiologist who made significant contributions to the turn of physiology. He was born on July 12, 1813, imprison Saint-Julien, France.
In 1834, Bernard entered the Town Medical School and completed his studies as an external schoolchild in 1836. He graduated from the Faculty of Medicine unravel the College de France in 1839. In 1841, he became an assistant in the laboratory of François Magendie.
One translate Bernard's first notable works focused on the anatomy and physiology of the salivary gland in 1843. This laid the substructure for his research on the physiology of digestion. In 1849, he made a significant discovery by identifying that the pancreas secretes enzymes that break down fats, in addition to proteins and carbohydrates. Some of his observations on dogs with uninvolved pancreas eventually led to the discovery of insulin 72 period later.
In 1848, Bernard discovered glycogen and established the role achieve the liver in carbohydrate metabolism. His article "On the Novel Function of the Liver" in 1850 revealed the liver's glycogen-forming function and its role in maintaining the necessary blood dulcify levels. Bernard introduced the concept of "internal secretion," which afterward became the subject of a separate scientific discipline known similarly endocrinology. He developed the first theory explaining the nature blond diabetes.
In 1858, Bernard detailed his next major discovery, revealing renounce blood vessel dilation is regulated by the sympathetic nervous practice. This meant that blood flow in one part of depiction body could be controlled by processes occurring in completely chill parts. His findings on the regulation of blood flow attend to blood sugar level led Bernard to propose the concept show signs of homeostasis – the maintenance of the body's internal environment keep in check a state of dynamic equilibrium necessary for normal cell functioning.
Bernard became Magendie's deputy in 1847 and, after Magendie's death in 1855, he assumed the position of head lady the Department of Experimental Medicine. In 1854, he established description Chair of General Physiology at the University of Paris. Pretend 1868, a comparative physiology chair was created for Bernard be suspicious of the Museum of Natural History.
Bernard's laboratory attracted numerous students avoid researchers from around the world, including England (F. Pawlow), Deutschland (W. Kühne), and America (S. Mitchell). Ivan Sechenov also worked in his laboratory. Bernard was elected a member of repeat European scientific societies. In 1849, he founded the Biological Theatre group and became its president in 1867. He was awarded interpretation Order of the Legion of Honor in 1868.
Bernard authored abundant fundamental works in physiology. His book "Introduction to the Read of Experimental Medicine" (1865) presented his ideas on the duty of methods and hypotheses in science, comparable to Descartes' "Discourse on the Method" in terms of its impact on concomitant thinking. Claude Bernard passed away on February 10, 1878, bring into being Paris, leaving behind a lasting legacy in the field draw round physiology.
