What are burkinje fibers?

burkinje fibers are specialized muscle fibers found in the heart. They come from the atrioventricular bundle and reach into the chambers. Their function is to pass the pulses from the bundle to the chambers and cause contraction. They do at speed between three ft (one m) and 12 ft (four m) per second, causing the contractions of the chambers almost instantaneous. The burkinje fibers are stretched along the tissue of heart muscle tissue, starting with an atrioventricular node. Then they proceed down to the middle part of the heart and branch on both sides of the bottom, curving along the outer edge of the endocardial wall. This in turn causes the chambers to withdraw. Contracting contracts produce enough power to eject blood from the heart, which is necessary for circulation. The pulmonary circulation comes from the right ventricle and the system circulation comes from the left. If it is colored and viewed under the microscope, the burkinje fibers will look larger and lighter than the surrounding muscle tissue.

named after Czechoslovak anatomist Jan Evangelista Purkyne, the burkinjova fibers were discovered in 1839. Purkyne, spectified alternatively in Burkinje, also discovered burkinje cells , which are large neurons located in Cerebellum. In addition, it is attributed to the discovery that the red color objects disappear faster in weak lighting conditions than those that are blue. This is known as the effect of burkinje .

Burkinje was very active in the scientific community of his time. He created the term plasma , which refers to the bloods of all suspended cells and protoplasm , a substance in the cells. In 1823 Burkinje published a post on the structure of fingerprints and their anatomical make -up. Although his primary focus was physiology, he also carried out raids into the world of experimental psychology.

During his life, Purkinje made at least six major discoveries that his name now bear. At the beginning of the 17th centuryHe was so famous that any letters that were addressed had to simply contain his name and the word "Europe". It is said that he founded the world's first physiology department, followed shortly afterwards the first physiological laboratory.
