Abstract

The article presents the anatomical features of the hip flexor muscles in shalaika, which are absent in the available literature. The points of fixation of the large lumbar, iliac, sartorial and scallop muscles have been established. The material for the research was a sectional material - pelvic limbs (n=IX), selected from adult canine hybrids (shalayki), without external signs of pathologies of the musculoskeletal system.It was found that the tensioner of the wide fascia of the thigh has two parts with a versatile direction of bundles of muscle fibers: in the cranial part – from the muckle along the cranial edge of the quadriceps femoris downward, and in the lateral part – from the place of transition of the muckle to the wing (cranial edge), along the middle gluteus muscle in the caudal direction, to the fascial node, on the where the broad fascia proper, the gluteal fascia and the superficial gluteal muscle converge. This circumstance undoubtedly affects the function of this muscle, i.e. together with the flexion of the hip joint, the muscle strains the broad fascia of the thigh itself, interacts in synergy with the gluteal fascia and the kneecap.Fusing the fascia in the distal part with the quadriceps femoris muscle, it creates a pressor effect on this muscle and helps it to unbend the knee joint. It is shown that the tailor's muscle is highly developed and consists of two heads. The cranial head is involved in the flexion of the hip joint, but at the same time in the extension of the knee joint. The caudal head – femoral part is directed along the medial surface of the thigh along the medial condyle of the femur, and the tibial part – along the medial surface of the capsule of the knee joint and the medial condyle of the tibia, which indicates adduction of the hip in the knee joint area and possibly optionally acts as a knee flexor.
