Abstract
The article presents anatomical and topographic features of the posterior femoral group of hip
extensors in small cattle – sheep of Dagestan mountain breed, and also clarified the topical
features of anatomical bone formations of the sciatic hillock, in particular the presence of "dorsal,
lateral and medial outgrowths" on it. The material for the research was a sectional material - pelvic
limbs (n=8), selected from adult sheep of the Dagestan mountain breed, without external signs of
pathologies of the musculoskeletal system. The methods of fine macro- and microanatomic dissection
under the control of a binocular magnifier «Micromed HR 350 S» were used, followed by functional
analysis of the studied structures and skeletotopic projection of points of attachment of parts
of the muscle. The established sites of attachment of the semi-tendon muscle confirm its functions
as an optional extensor of the hip and metatarsal joints, and the main function is associated with
flexion, pronation and adduction of the knee joint and, accordingly, the proximal part of the limb.
The revealed anatomical features of the studied muscles may reflect their functional relationship.
The data obtained are reference in assessing the structural and functional state of the muscles
of the posterior femoral group of hip extensors in domestic sheep.
