Anatomical and topographic features of fascial formations of the glutealfemoral region in cattle

Abstract

The article presents anatomical and topographic features of the myofascial formations of the gluteal-femoral region in cattle, which are not reflected in the available literature. It has been shown that the deep femoral fascia between the underlying muscles forms its fascial nodes, from which the "intermuscular fascial plates" extend into the depths, represented by partitions of dense connective tissue passing between the muscles. The deep fascia of the thigh tightly fits the structures of the thigh, and at the same time, the gluteal-biceps, slender and tailor muscles are enclosed between its outer and inner sheets. The outer sheet of the deep fascia, from the lateral surface, covers the tensor of the wide fascia of the thigh, fuses with the surface of the gluteal biceps muscle, and on the border with the semi-tendon muscle it forms a powerful caudo-lateral fascial node. The material for the research was sectional material – pelvic limbs (n=10), selected from calves of the black-and-white Holstein breed, without external signs of pathologies of the musculoskeletal system. The methods of fine macro- and microanatomic preparation under the control of a Micromed HR 350 S binocular magnifier, biomechanical modeling followed by functional analysis of the studied structures, as well as the manufacture of frozen cuts according to N. I. Pirogov were used. It is advisable to use the original data obtained in matters of veterinary and sanitary expertise in the morphological substantiation of the quality of the meat raw materials obtained.
