Although its history is complicated, today's anatomical nomenclature, including muscle terminology, has acquired a system of naming using epithets. The objective of this literary research paper was to ascertain the founder of modern muscle terminology. The texts of four anatomists, Galen, Andreas Vesalius, Jacobus Sylvius, and Gaspard Bauhin, who have all been identified as being influential in the establishment of early modern anatomy and its nomenclature, were analyzed. Particular emphasis was given to the naming method, and to the consistency of that method...

The medial preoptic area (MPOA), an anterior part of the hypothalamus, is one of the most important areas for the regulation of instinctively motivated behaviors, such as parental behavior, mating behavior and aggression. Consistent with its role in reproductive behaviors, the MPOA abundantly expresses gonadal steroid hormone receptors and shows distinct sexual dimorphism in its morphology. Despite the functional importance of the MPOA, the anatomical demarcations of the mouse MPOA subregions have been confusing and remained undefined because of their heterogeneity and complexity...

Gantzer muscles are variant muscles in the anterior forearm inserting into the flexor pollicis longus or, less often, the flexor digitorum profundus. The presence of Gantzer muscles can cause a compressive neuropathy affecting the anterior interosseous nerve (Kiloh-Nevin syndrome). These muscles must also be considered when anterior forearm fasciotomies are performed for the management of acute compartment syndrome. In this case report, a novel Gantzer muscle originated from the flexor digitorum superficialis as well as the investing fascia of the brachialis muscle; the latter site is a novel proximal attachment not previously reported...

The inner structure of the pons contains several layers of transverse and vertical fibers and many nuclei. The vertical bundles are described as fibers of the corticospinal tract, corticonuclear tract, frontopontine tract and parieto-temporopontine tract organized in three layers. The aim of this study was to investigate the structure of the vertical bundles in the ventral pons using the modified Klingler method. Ten brain stem specimens were investigated. Specimens were fixed in 10% formalin, frozen for 24 h to separate nerve fibers by ice crystals, and then unfrozen again in 10% formalin solution...

α-Synuclein, the major component of Lewy bodies (LBs) and Lewy neurites (LNs), is expressed in presynapses under physiologically normal conditions and is involved in synaptic function. Abnormal intracellular aggregates of misfolded α-synuclein such as LBs and LNs are pathological hallmarks of synucleinopathies, including Parkinson's disease (PD) and dementia with Lewy bodies (DLB). According to previous studies using pathological models overexpressing α-synuclein, high expression of this protein in neurons is a critical risk factor for neurodegeneration...

The present study aimed to give full morphological insight into the oropharyngeal cavity of Eurasian hoopoe at the level of gross morphology in addition to ultrastructural inspection including light- and scanning electron microscopy. The oropharyngeal cavity has a triangular appearance with a very long rostrally located beak, helping the bird achieve its feeding mechanism. The floor of the oropharyngeal cavity is divided into three parts; a pre-lingual part with a pre-lingual fold, a lingual part containing a rudimentary triangular tongue, and a laryngeal part, which contains a small elevated laryngeal mound...

Nisin is a food preservative produced by Lactococcus lactis subsp. lactis. Previous blood biochemical research revealed that nisin has physiological effects in mammals; although the site of action has yet to be identified, keratinocytes have been proposed as a possible target. In this study, we investigated whether nisin affects keratinocytes by examining the effects on eukaryotic intermediate filaments in HaCaT human keratinocytes. Treatment with 93 μg/ml nisin for 24 h decreased the localization of the intermediate filament proteins cytokeratin (CK)5 and CK17 at the cell periphery, which were distributed in a limited area in a ring- or net-like shape...

A typical cochleogram was plotted to investigate hair cell densities as a percentage along the whole length of the basilar membrane (BM) of the rabbit, the length of the BM and the width of the organ of Corti. We generated surface preparations of cochlea from adult, healthy New Zealand White (NZW) rabbits. The numbers of inner hair cells (IHCs) and outer hair cells (OHCs) were counted from images acquired from a digital camera attached to an Olympus light microscope with a scale of 100 μm as a primary unit drawn continuously, and the numbers of IHCs and OHCs were converted to densities at 10% intervals along the length of the cochlea...

A major component of tooth innervation is made of capsaicin-sensitive primary afferents (CSPA). These fibers play a key role in tooth pain and inflammation; little is known, however, about the role of CSPA in tooth eruption. The aim of this study was to examine the role of the capsaicin-sensitive afferents in the process of eruption of intact rat incisors. CSPA fibers in several rat groups, were subjected to one of the following experimental procedures: systemic chemical ablation, systemic ablation followed by chemical sympathectomy and localized activation...

Chronic testicular pain remains an important challenge for urologists. Investigation of the innervation of male gonads thus becomes essential for deepening our understanding of their regulatory roles in male reproductive physiology and pathophysiology. Studies of testicular innervation are mainly limited to the intratesticular peptidergic nerves of the testis by immunohistochemical and acetylcholinesterase histochemical investigations in some animals. Little is known about the detailed, overall distribution in general experimental animal testis...

Parkinson's disease is caused by damage to substantia nigra dopaminergic neurons. Factors such as oxidative stress, inflammatory factors, and acetylcholinesterase activity may induce this disease. On the other hand, crocin-one of the active ingredients of saffron-has anti-oxidant and anti-inflammatory properties. This study was performed to evaluate the protective effect of crocin to decrease dopaminergic neuron damage and Parkinson's disease complications induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)...

The increase in autoimmune diseases in recent years has drawn attention back to the thymus, with new approaches to improve and/or restore immune function being investigated. As the primary lymphoid organ responsible for functional T cell development, studies on the pre-/post-natal development of this organ and T lymphocytes in human and other species are of special interest. During our screening studies we observed structures that had not been described or mentioned previously, and named them "epitheliostromal sheaths"...

We developed a technique to analyze the high-resolution three-dimensional (3D) structure of seminiferous tubules. It consists of segmentation of tubules in serial paraffin sections of the testis by marking the basement membrane with periodic acid-Schiff or a fluorescent anti-laminin antibody followed by 3D reconstruction of tubules with high-performance software. Using this method, we analyzed testes from mice at different ages and accurately elucidated the 3D structure of seminiferous tubules, including the number and length of tubules as well as the numbers of connections with the rete testis, branching points, and blind ends...

The pampas deer (Ozotoceros bezoarticus) is a medium-sized deer that weighs 20-40 kg. Historically, it was a widely distributed species that occupied a wide range of open habitats, including pastures, pampas, and Brazilian savanna. However, it is currently considered to be a species at risk of extinction. Anatomical descriptions of the arterial supply are very useful when working with exotic mammals. Knowledge of the locations, the distribution pattern, and the anatomical relationships of the arteries is required when performing any intervention...

Coronary vessel development has been investigated in avian and mouse embryonic hearts. Quail embryos are a useful tool to examine vascular development, particularly because the QH1 antibody and transgenic quail line, Tg (tie1:H2B-eYFP), are useful to trace endothelial cells. However, there are only a few descriptions of the quail coronary vessels. Using ink injection coronary angiography, we examined the course of coronary vessels in the fetal quail heart. The major coronary arteries were the right and left septal arteries, which, respectively, branched off from the right and left coronary stems...

The pancake kidney (PK) is a rare type of renal anomaly in which both kidneys completely fuse without an isthmus. In the previous reports, PKs have double ureters and are located in the pelvic cavity. We encountered a rare case of PK with a single ureter, which is located in the left retroperitoneal space, in a 95-year-old female cadaver, which was detected during a dissection course. In our case, the major calyces joined to form a single renal pelvis, which continued as a single ureter. To the best of our knowledge, this is the first report on PK with a single ureter that is located not in the pelvic cavity but in the retroperitoneal space...
