Anatomical and topographic features of the hip flexor muscles in a large white pig

One of the most important tasks of the agro-industrial complex of the Russian Federation at this stage is to solve the problems associated with increasing meat resources, providing the population with high-quality meat products. The development of domestic beef cattle breeding will create conditions for the sustainable development of rural areas, which is one of the most important strategic goals of state policy, the achievement of which will ensure food security, increase the competitiveness of the Russian economy and the well-being of citizens. The article presents the anatomical features of hip flexors (flexors) in a large white breed pig. It has been shown that the main flexor of the hip joint in a pig is the iliolumbar muscle. It is quite fleshy, large, whereas the small lumbar muscle is less developed and is covered by the large lumbar muscle. Among the heads of the iliac muscle, the lateral head is well differentiated on the ventral surface of the iliac bone body, whereas the medial one is represented as a thin, small muscle located between the tendon ends of the large and small lumbar muscles. The material for the research was a sectional material – pelvic limbs (n=10), selected from pigs of a large white breed, without external signs of pathologies of the musculoskeletal system. Methods of fine macro- and microanatomic dissection, biomechanical modeling with subsequent functional analysis of the studied structures were used. New data on the anatomical and topical features of hip flexors in a large white pig are presented, which are determined by the mechanism of the static locomotor act of the animal. The points of fixation of the long and short tendons of the tailor's muscle have been established, which, covering and covering the distal part of the ilio-lumbar muscle from the ventral surface, optionally perform the function of a supporting ligament for this muscle.
