On the issue of the system organization of tetrapod humerus

Abstract

The main aim of the research is to study the system organization of the dog’s humerus. 78 humeral bones of not purebred dogs (D=R) were studied using osteometry methods. The data obtained were normalized by the value of the transverse diameter of the diaphysis. The data analysis was performed using the principal components method with the rotation of Equamax normalized taking into account the lateralization of bones. As a result, it was found, that the basis of the humerus systemic organization is formed of structures, responsible for taking the animal's body weight. The revealed latent morphofunctional asymmetry of the dog's shoulder bone systemic organization is manifested on the right bone - by high values of factor loads on the anatomical structures, which provides flexion/extension in the joints; for the left shoulder bone - on the structures providing rotations.
