Vascularization of the muscles of the shoulder joint of a Dorper sheep

Abstract

The angioarchitecture of the intraorgan arterial bed of the studied muscles of the thoracic limb of the Dorper sheep is characterized by a modular type of structure. The direction of the arteries of the first and second orders inside the muscles usually does not correspond to the course of the muscle bundles, and their intrasystemic anastomoses form a large-loop network with polygonal cells. Vessels of the third order cross bundles of muscle fibers at right angles, and those of the fourth order are located parallel to the latter, forming relatively dense fine-loop networks elongated along their course.
