[So-called muscular "bridges" and their interrelationship with blood vessels]

Abstract

Fifty hearts of corpses of humans of different age groups were studied by means of macro-microscopical anatomical dissection of muscle fibres and cardiac blood vessels. The muscle bridges were found over the coronary arteries in all preparations of the heart. They were most frequently met on the anterior interventricular branch of the left coronary artery. The topography of muscle bridges is described and the miocardium muscle bundles participating in their formation are revealed. The character of the course of fibres in the muscle bridge is related to the course of the fibres of the muscle bundle forming it.
