Anatomical and topographic features of the flexor muscles of the hip joint in the common lynx

Abstract

The article presents anatomical features of hip flexors (flexors) of the common lynx, which are absent in the available literature. The points of fixation of the large lumbar, iliac, sartorial and scallop muscles have been clarified. The research was carried out at the Department of Anatomy and Histology of Animals named after Professor A.F. Klimov of the Moscow State Academy of Veterinary Medicine and Biotechnology – MBA named after K.I. Scriabin. The material for the research was a sectional material - pelvic limbs (n=6), selected from the common lynx, without external signs of pathologies of the musculoskeletal system. We used methods of fine macro- and microanatomic dissection under the control of a binocular magnifier "Micromed HR 350 S", followed by functional analysis of the studied structures and skeletotopic projection of points of attachment of muscle parts. At the same time, we clarified the topical features of anatomical formations on the pelvic (unnamed) bone – "median roughness of the pubic bone" "roughness of the cranial accessory abdomen of the scallop muscle"; "roughness of the scallop muscle" on the femur. It was found that in lynx, the flexors of the hip joint include a complex of muscles – the tensor of the wide fascia of the thigh, the ilio-lumbar, tailor's and scallop muscles. The strainer of the wide fascia of the thigh, fusing in the distal part of the fascia with the quadriceps muscle of the thigh, creates a pressor effect on this muscle and helps it to unbend the knee joint. The revealed anatomical features of the studied muscles are the reference in assessing the structural and functional state of the hip flexor muscles in the common lynx.
