ANATOMICAL AND TOPOGRAPHIC FEATURES OF THE GLUTEAL MUSCLE GROUP IN BLACK-AND-WHITE CATTLE

Abstract

The article presents the anatomical features of the gluteal muscle group in cattle. It was found that the main extensor is the middle gluteal muscle. This is the most powerful muscle in the gluteal group, of a dynamic type, has an extensive area of attachment to the muclock, iliac crest, sacral tubercle and the adjacent surface of the iliac wing, as well as to the lateral surface of the spinous processes of the first vertebrae of the sacrum. The material for the research was a sectional material – pelvic limbs (n=10), selected from cattle of a black-and-white Holstein breed, without external signs of pathologies of the musculoskeletal system. The methods of classical and fine macro- and microanatomic dissection were used. The topological features of anatomical formations on the pelvic (ring) and femoral bones are shown – the "line of the double muscle", the "line of the external locking muscle" on the ventral surface of the sciatic bone; "pad of the middle gluteus muscle", "pad of the piriformis tendon", "roughness of the additional gluteus muscle", two "roughnesses of the deep gluteus muscle" located on the large trochanter of the femur.
