Anatomy, functional anatomy and morphometrical study of forelimb column in Asiatic cheetah (Acinonyx jubatus venaticus)

Abstract

The Asiatic cheetah (Acinonyx jubatus venaticus) is one of the most endangered members of the family Felidae in the world. However, there isn’t enough information about anatomy and functional anatomy of its bones and muscles. The aim of this study was to investigate the anatomy, morphometry and function of forelimb column (humerus, radius, ulna). The carrions of five adult Asiatic cheetahs were collected from the desert. Column bones of forelimbs were studied anatomically and relationship between their angles, tubers and origin and insertion of some important muscles in the Felidae were evaluated. Also some important parameters were measured. Results showed that very important characters of this animal were referred to their articular surfaces and tubers of their bones. Also the length and diameter of column bones and angles between origin and insertion of their muscles, especially brachioradialis muscle, play a high role in their anatomical function.
