Salivary gland tumors are a rare and heterogeneous group of neoplasms of the head and neck region. The mixed category of these tumors include the following entities: pleomorphic adenoma (PA), carcinoma ex pleomorphic adenoma (CEPA), salivary carcinosarcoma (CS), and metastasizing PA (MPA). The most common benign tumor of the salivary glands is PA.

This condition poses significant public health challenges, affecting individuals, healthcare systems, and economies worldwide. Among its numerous complications, ocular surface disease (OSD) is a significant concern, yet understanding its pathophysiology, diagnosis, and management remains challenging.

One of the essential properties of these materials should be the biocompatibility. The aim of this study was to evaluate the biocompatibility of some orthodontic biomaterials like stainless steel archwires, brackets and NiTi (nickel-titanium alloy) coil springs.

Another type of encephalopathy associated with chronic ethanol consumption is represented by the Marchiafava-Bignami malady or syndrome, an extremely rare neurological disorder, which is characterized by a demielinization of corpus callosum, extending as far as a necrosis.

After giving off a few thin branches, at the lower part of the esophagus and the cardiac region of the stomach, the anterior vagal trunk divides into its main branches: four or five consecutive direct branches which supply the upper part of the lesser curvature; these nerves do not form plexuses and thus, they may be individually dissected. One of the branches is stronger than the others and is called the principal anterior nerve of the lesser curvature (anterior nerve of Latarjet).

The aim of our study was to identify the most important anatomical landmarks in the cephalometric evaluation of Class III patients and to clarify the morphological characteristics of these cases. A group of 10 Class III orthodontic patients was evaluated in this study. The control group consisted of 10 patients with average occlusion and skeletal characteristics.

Afferent branches get to this plexus from the vagus nerve, splanchnic nerves and the right phrenic nerve; efferents leave for viscera through periarterial plexuses and the retroportal nerves. The coeliac plexus ganglia - coeliac, superior mesenteric, aorticorenal - are prevertebral ganglia that receive the preganglionic sympathetic fibers brought by the splanchnic nerves from the thoracic spinal cord.

Enteric nervous system (ENS) is a network made of neuronal cells and nervous fibers. There are two plexuses: myenteric of Auerbach and sub mucous of Meissner and Henle. Many substances are involved in neurotransmission at ENS level.

Pre visceral ganglia are sympathetic ganglia chains between the lateral vertebral sympathetic chain and viscera. Our study is made in the anatomy lab on 30 adult human bodies, one of new born and 10 human fetal specimens with crown-rump lengths from 9 to 28 cm.

It was studied the morphological parameters about diameter and number of the atrial orifices of the pulmonary veins. The number of the orifices and their diameter depends on the lungs weight.

The study was done on 50 corpses using the dissection method. We are looking after torsion variants of pneumogastric nerves around the esophagus, morphological variability of the periesophageal pnemogastric plexus among witch the pnemogastric nerves loose theirs individuality through the mixture and the anastomoses of the fibers and the morphological variability of abdominal branches of the nerve, grouped by us in anterior and posterior branches.

Morphological variability of the colic branches derived from the mesenteric arteries (superior right colic artery -- 98%; middle right colic artery -- 88%; inferior right colic artery -- 100%; middle colic artery - 36%; superior left colic artery -- 100%; middle left colic artery -- 50%; inferior left colic artery -- 100%) allows us to give out a morphogenetic supposition related their ramification and number. Analyze of the results guide us to a tentative of setting down the vascular territories of the colon.
