Anatomical and Clinical Considerations of the Pectoralis Tertius Muscle in Man International Journal of Morphology
del Sol,Mariano; Vásquez,Bélgica.
The anatomical variation of the major pectoral muscles is infrequent, namely the agenesis of the pectoralis major muscle due to the morpho-functional alterations it causes. On the other hand, he presence of -supernumerary - pectoral muscles is not common and its physiological, clinical or surgical importance will depend on the stage of its development. The important aspect is that these muscles, while crossing the anterior wall of the axila and inserting in the humerus, may confuse or difficult surgical access to the content of the axillary fossa. Pectoralis tertius muscles were found in two dissected cadavers at the Topographic Anatomy of the Faculty of Medicine of the Universidad de La Frontera, Chile. These muscles were bilateral and independent of the...

Anatomical Characteristics of Deer and Sheep Lumbar Spines: Comparison to the Human Lumbar Spine International Journal of Morphology
Wang,Yang; Liu,Ting; Song,Liang-Song; Zhang,Zhi-Xin; Li,You-Qiong; Lu,Lai-Jin.
Deer and sheep spines are often used as models of the human spine. A prerequisite for the use of animal models is information regarding the interspecies differences in the parameters of general interest. This would clarify the limitations of each animal model and substantiate the applicability of the obtained results to humans. Since sufficient data appear to be currently unavailable, we sought to investigate the feasibility of using deer and sheep as animal models for studies on the human spine. The objective of this study was a thorough comparison of the anatomical parameters of deer and sheep spines with those of the human spine. We employed three-dimensional reconstructions of computed tomography images, generated using figure analysis software, which...

Unver Dogan,Nadire; Fazliogullari,Zeliha; Uysal,Ismihan Ilknur; Seker,Muzaffer; Karabulut,Ahmet Kagan.
Three foramina can be identified in the greater wing of the sphenoid bone: The foramen rotundum (FR), foramen ovale (FO) and foramen spinosum (FS). In addition, there may be another foramen called foramen ovale accessorium or foramen vesalius (FV) which connects the middle cranial fossa to the fossa pterygoidea (pterygoid fossa). It is described as an opening with smooth walls in front and medial to foramen ovale which leads to an oblique channel directed towards the fossa pterygoidea. FV was present between FO and FR in 14 (31.8%) of 44 dry and 6 (33.3%) of 18 cadaver skullbase sides (total 20 (32.3%) of 62). The diameter values of foramens on both the right and the left side were observed to be almost symmetrical. FR's distance from the midline on the...

Oliveira,Carla Lívia Santos de; David,Gustavo Serra; Carvalho,Michelly de Oliveira; Dornelas,; Araújo,Sandra; da Silva,Nailton Cavalcante; Ruiz,Cristiane Regina; Fernandes,Juliana Ruiz; Wafae,Nader.
In humans, the right coronary artery is dominant. However, we did not find any citations in the literature concerning anatomical indicators of dominance among dogs. We used 30 hearts from mongrels of both sexes, fixed in 10% formalin. The branches of the coronary arteries were dissected with special attention to the levels that were considered to be reference points. In 96.7%, the circumflex branch of the left coronary artery reached or went beyond the crux cordis. The subsinuosus interventricular artery, ended before reaching the apex in 21 cases, at the apex in five cases and after the apex in four cases. The paraconal interventricular artery, ended before reaching the apex in two cases, at the apex in 11 cases and after the apex in 17 cases. The region...

The past findings confirm that the Rectus Capitis Posterior minor (RCPmi) is connected to the cervical spinal dura mater via the Myodural Bridge (MDB) through the posterior antlanto-occipital interspace. It is hypothesized to perform some functions. Furthermore, some clinical studies found that the pathology of RCPmi might be related to chronic headaches. But few studies were related to the morphological parameters of the RCPmi. It would be conducive to performing clinical researches on the RCPmi and MDB. To explore the optimal section for measuring the RCPmi by MRI and provide imaging anatomy parameters of the RCPmi for clinical research. The RCPmi was measured in the dissection of 10 formalin-fixed cadaver specimens. The morphological parameters of the...

ANATOMICAL RELATIONSHIP BETWEEN VERTEBRAL ARTERIES AND CERVICAL VERTEBRAE: A COMPUTERIZED TOMOGRAPHY STUDY International Journal of Morphology
Gonçalves Martins,Johnny Wesley; Pratesi,Riccardo; China Bezerra,Armando José.
Vertebral arteries ascend lateral to the cervical spine. Although non-contrasting tomographic studies have attempted to determine the anatomical relationship between these arteries and the spine, the presence and position of the former have yet to be clearly demonstrated. This study was thus aimed to determine the position of the vertebral arteries in relation to the midline, anterior and posterior planes of the vertebral body of each cervical vertebrae. Twenty six adult patients, without lesions that could distort normal anatomy, were employed as subjects and 52 vertebral arteries were analyzed. Two-dimensional computerized tomographies scans were conducted following the injection of an intra-venous contrast. Statistical analyses evaluated the differences...
