Anatomics comparative aspects of head bones of domestic animals and adult human

Abstract

Among the anatomical structures that make up the body of individuals, there are the bones of the head (skull and face) belonging to the axial skeleton, resulting from the union of even and odd bone structures that form a rigid box, which supports and protects part of the central nervous system. Due to the functional importance of the head, this study aimed to describe the bones of this region of some domestic animals, including canines, horses and bovines, as well as humans, and also emphasize the structural similarities and locations in these different adult species. For this, photographic records were made for further descriptions of anatomical bone pieces from the collection of the Human and Veterinary Anatomy Laboratory of the University of Franca. The results were expressed descriptively, following the Nomina Anatomica Veterinaria. Regardless of the species, all presented bones incisor, nasal, maxillary, lacrimal, zygomatic, frontal, parietal, temporal, occipital, palatine, vomer, pterygoid and sphenoid bones, however, with varied sizes and shapes. Given the recommended methodology and the data obtained, it is possible to infer that the anatomical morphological distinctions between head bones of canine, equine, bovine and human are directly related to the functional, evolutionary, adaptive and postural aspects of each species.
