Leonardo da Vinci and human anatomy
Introduction
At the beginning of the 16th century Leonardo drew the various stages of human development, his anatomy sketches were the first exact observations about the nature of the human being. Leonardo as one of the first artists, dissects the bodies, the knowledge he acquires about them serves him for his drawings, to improve his expressive form, knowing that the facial expression of a person is mainly determined by two elements the eyes and commissure of thelips.
Developing
With his anatomical studies he sought to represent and understand the human body in all its dimensions and as an organic unit. His first object of study of anatomy was the head of man, carefully uses skulls of all his perspectives to be ablecall common sense, here believes that the center of the senses is.
Today this section is located the third cerebral and hypothalamus nucleus, the most important organic functions regulation center. When autopsy is prohibited in humans, riot monkeys and bears, the knowledge that acquires from them moves them to the human being. In 1503 Leonardo discovers that in the Florentino hospital in Santamaría, dissections of bodies of denied people who were prohibited the funeral are regularly carried out.
Leonardo gets permission to practice autopsies, in the following years he dissects more than 30 bodies to systematically study the body parts, reveals organs, muscles and bones and draws them from different angles to document them, Leonardo uses the mill technique andStart through the abdominal wall, exposing the stomach and intestinal tract first, and then advance to the internal organs leaving evidence of each thing in their drawings.
Even organs whose function was unknown as the appendix. As the first anatomist, he draws the spine in detail reproducing the curvature as the number of vertebrae, but since Leonardo was not a doctor, so the hospital denies the bodies, force continues his anatomical research with animal corpses, studying the heart ofA pig that unlike previous opinions was the first to describe the heart as a muscle and as the center of the blood system.
Dethroning the postulates of the former Greek Galeno, who endured untouchable since the second century. Da Vinci was also a pioneer in his analysis of the size of the veins and arteries, and since these ‘branches’ decrease in each division as they move away from the heart, as with the rivers and streams. He devised making wax molds from the ventricles of the brain, discovered how blood runs through the whole body, carrying food and removing waste.
Through autopsia he managed to demonstrate that the heart has four compartments divided by valves and membranes, also estimating that they should have different functions that justified these separations ‘Leonardo’s greatest achievement in his heart studies and, in fact, in all his anatomical works. It was his discovery of the way in which the aortic valve works, a triumph that was confirmed only in modern times ’. A team of doctors from the University of Oxford managed to prove that the aortic valve functioned as he said.
conclusion
Leonardo is not the founder of modern anatomy, but one of those who laid the bases. In 1516 he moved to France and lives the last years of life, compares life with the light of a candle and when his clear glow dies he becomes dark smoke, describes the arteriosclerosis, perceives that the blood vessels of the body of a young person of a young personAs straight and smooth, but over time they deform and swell, in 1519 Leonardo dies because of the disease that he had studied latest arteriosclerosis, which caused a stroke.
