Abstract

The article presents the morphological and functional characteristics of the powerful knee extensor in the noble spotted deer. 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 objects of research were mature noble spotted deer (n=5). Topical features of anatomical formations on the pelvic (nameless) and femoral bones were revealed – the site of the lateral head of the quadriceps femoris muscle on the large trochanter of the femur; «the lateral site for fixing the rectus quadriceps femoris muscle », «the crest of the rectus femoris muscle» on the ilium. When studying the architectonics of the quadriceps femoral muscle, the points of attachment of its heads, the orientation of the bundles of its muscle fibers, it can be argued that the muscle, being multi–articular, is able to perform extension and abduction of the knee joint, and its straight head – flexion and supination of the hip joint. Equipped with lateral and medial tendons, the intermediate head, with a significant degree of probability, implements the positional stability of the kneecap on the femoral block.
When analyzing the phases of the static-locomotor act, it was found that when the fulcrum changes, the function of the muscle changes, which may be due to the organ and biomechanical specificity of topographically coupled joints.
The revealed anatomical features of the quadriceps femoral muscle are the reference in assessing the structural and functional state of the knee joint in the noble spotted deer and diagnosing its pathologies associated with impaired functioning of its ligamentous-muscular system.
