Abstract

ÖZET

Çeşitli tür ve ırklardan hayvanların iskelet sistemine ait kemiklerinin yapısal, mekaniksel ve histolojik özellikleri ile ilgili bir takım araştırmalar yapılmıştır. Ancak bu çalışmaların iskelet sisteminin önemli bir bölümünü oluşturan ön ve arka bacak uzun kemiklerine ait osteometrik verilere yönelik incelemeleri yeterli oranda kapsamadığı görülmüştür. Bu çalışmada; erişkin tavşanlarda incelenen gelişmiş uzun kemiklerin, cinsiyet farklılığın göz önüne alınarak homotipik varyasyonunu ortaya koymak amacı ile morfometrik değerlerin elde edilmesi, bu değerlerin canlı ağırlık ile olan ilişkisinin incelenmesine kaynak oluşturacak verilerin belirlenmesi amaçlanmıştır. Bu amaçla; 15 dişi- 15 erkek erişkin tavşan canlı ağırıkları ve ön ve arka bacaklara ait uzun kemiklerindeki (humerus, antebrachium, femur, tibia, fibula) osteometrik olçümler alınmıştır. Sonuç olarak; tavşanlarda ön ve arka bacak uzun kemikleri bakımından sağ ve sol değerlerin birbirine çok yakın ve istatistiki açıdan homotipik varyasyon göstermediği, aynı zamanda cinsiyetin önemli bir faktör olmadığı ifade edilebilir. Bununla birlikte, söz konusu kemikler simetrik olması bakımından kontrol şartları oluşturmak üzere kullanılabilir.

Anahtar Kelimeler: Tavşan, uzun kemik, homotipik varyasyon

 

STUDIES ON HOMOTYPIC VARIATION OF FORELIMB AND HINDLIMB LONG BONES OF RABBITS

ABSTRACT

Until recently, a number studies have been conducted on the structural, mechanical and histological properties on the bones of the skeletal system of various animal species and breeds. However, it was found out that the studies on obtaining osteometric data on the long bones of the forelimb and hindlimb, which comprise an important part of the skeletal system were limited and insufficient. The aim of this study was to obtain morphometric data in order to find out the homotypic variation of long bones on mature rabbits considering the sex variations, and a data source which will enable to study the correlation between these data and live weight values. For this reason, osteometric values of live weights, long bones of forelimb and hindlimb (humerus, antebrachium, femur, tibia, fibula) of 15 male and 15 female rabbits are measured. As a result, it can be stated that the values of the long bones of forelimb and hindlimb of the rabbits are very close and they don't reveal homotypic variations statistically. It is also concluded that sex variation is not an important issue. In addition, such symmetric bones can be used to from a control environment.
