Fibers: Swedish translation, definition, meaning, synonyms

Their function is to send nerve impulses to the cells in the ventricles of the heart and cause them to contract and pump blood either to the lungs or the rest of the body. The Purkinje fibers are functional conducting fibers, that are comprised of electrically excitable cells and are larger than the normal myocardial fibers. The Purkinje fibers are of the huge number of mitochondria and which fibers conduct cardiac action potentials more speedily and efficiently than any other cells in the heart. Purkinje fibers from dogs and sheep are the most frequently used; however, fibers have also been obtained from other animals such as calves, pigs, goats, and rabbits.

They are a part of the relaying system of electrical signals in the heart, which determines the rate at which the cardiac muscles contract and relax, or in other words, the rate at which the heart ‘beats’.
