Структурный адаптогенез скелета конечностей животных при различной статолокомоции

Структурный адаптогенез скелета конечностей животных при различной статолокомоции

Abstract

Методами анатомического препарирования, обзорной рентгенографии, световой, электронной растровой микроскопии и морфометрии изучено структурно-функциональное состояние бедренной кости у животных разных таксономических групп, отличающихся морфофункциональным типом конечностей (стопо-, пальце-и фалангохождение). Установлены как общие закономерности структурной организации бедренной кости у животных различных таксономических групп (норка, собака, свинья), так и видоспецифические признаки её строения, обусловленные статолокомоторным механизмом конечностей. Выявлено, что костная структура в изучаемых костях у стопоходящих и пальцеходящих представителей по темпам дифференцировки опережает пальцеходящих. Ростовые процессы по периметру диафизарной трубки у всех исследуемых животных протекают неравномерно, что ассоциируется с данными, полученными на основании изучения микроархитектоники компактной костной ткани. Процесс структурного становления компактного вещества диафиза завершается раньше в тех отделах, которые испытывают основную статодинамическую нагрузку. Отмечено, что направление структурного адаптогенеза, выражающегося в количестве и форме остеонных систем, соотносительном распределении пластинчатого комплекса и остеонных структур, подчинено биомеханике двигательного поведения изучаемых животных, и в первую очередь механизму их статолокомоторного акта.

The structure-functional condition of the thigh bone in animals of different taxonomic groups with different morphofunctional type of extremities (planti-, fingerand phalanxgraded) has been studied using the methods of anatomic preparation, plain roentgenography, scanning electron microscopy and morphometry. The general principles of the thigh bone structure organization in animals of different taxonomic groups (mink,dog, hog), as well as specific features of its structure depending on the statolocomotion of extremities, have been established. It is found that the structure of bones under study in the plantigraded animals surpass that of the fingergraded ones by the rate of differentiation. The growth processes along the diaphysial tube in all the animals under study are irregular, this being associated with the data obtained as result of studies on the microarchitectonics of the compact bone tissue. The process of compact diaphysis substance development is being completed firstly in those sections which bear the main statodynamic load. It is pointed out that the structural adaptogenesis, which is expressed in the number and forms of osteon systems is subjected to the biochemistry of the motional behavior of the animals under study and, first of all, to the mechanism of their statolocomotional action.
