X-RAY EXEMINATION OF HIP JOINT`S BONES OF SOME BIRDS OF PREY

N. V. Druz

Abstract. Based on comparative anatomical analysis ,it is described,compared and analyzed the structure and development of hip joint`s bones of some species of Falconiformes and Owlformes.It was determined that the bones that form the hip joint of the investigated bird`s species are different in shape and size.It is presented morphological characteristics of X-rayed skeletal elements that form the hip joint ,and it was founded that the degree of bones have some interspecies differences,caused by various factors and features of biomorphological stato-locomotion.The internal structure of the proximal half of the femur and the area of glenoid cavity among the studied prey birds is different in location of trabeculae both of compact and spongy substance.Greater degree of the development of compact substance of the lateral or medial side of the femur shows the effect of higher functional loads on one or another direction of bone. Uniform development of compact substance of one or another side respectively indicates the uniform distribution of functional loads. 4 types of branching trabeculae are typical for X-ray structure of the glenoid cavity of the pelvic bone: compact,dense and depending on the loads on one or another substance - dense-compact and compact-dense.It also explains by the different functional load of body`s weight per this section of the hip joint.
