Parkinson’s disease (PD) is a neurodegenerative disorder that leads to motor and non-motor impairments, including tremors, bradykinesia, and rigidity. Current treatments, such as pharmacological therapies and deep brain stimulation, have efficacy and side effects limitations. Transcranial direct current stimulation (tDCS) is a non-invasive techniqu...

Photogrammetry scans has directed attention to the development of advanced camera systems to improve the creation of three-dimensional (3D) models, especially for educational and medical-related purposes. This could be a potential cost-effective method for neuroanatomy education, especially when access to laboratory-based learning is limited. The a...

White matter dissection (WMD) involves isolating bundles of myelinated axons in the brain and serves to gain insights into brain function and neural mechanisms underlying neurological disorders. While effective, cadaveric brain dissections pose certain challenges mainly due to availability of resources. Technological advancements, such as photogram...

The jugular foramen (JF) is located between the temporal and occipital bones. The JF is a primary pathway for venous outflow from the skull and passage of nerves. Variations are common in this region and may have clinical and surgical implications. To analyze the sexual dimorphism and JF morphology in skulls from Northeastern Brazil. 128 human skul...

The 3D stereoscopic technique consists in providing the illusional perception of depth of a given object using two different images mimicking how the right and left eyes capture the object. Both images are slightly different and when overlapped gives a three‐dimensional (3D) experience. Considering the limitations for establishing surgical laborato...

Hands‐on dissections using cadaveric tissues for neuroanatomical education are not easily available in many educational institutions due to financial, safety, and ethical factors. Supplementary pedagogical tools, for instance, 3D models of anatomical specimens acquired with photogrammetry are an efficient alternative to democratize the 3D anatomica...

Esta obra constituiu-se a partir de um processo colaborativo entre professores, estudantes e pesquisadores que se destacaram e qualificaram as discussões neste espaço formativo. Resulta, também, de movimentos interinstitucionais e de ações de incentivo à pesquisa que congregam pesquisadores das mais diversas áreas do conhecimento anatômico de difer...

Background Coronary arterial dominance and myocardial bridges have clinical implications, since a left dominant pattern associated to the presence of myocardial bridges is often associated to a higher incidence of arteriosclerosis and higher mortality by myocardial infarction. Objective To determine the presence and position of myocardial bridges...

Introduction: The posterior cerebral artery (PCA) is a vessel of the Circle of Willis. Variations are observed in the first segments of the PCA and its branches, especially in the thalamoperforating arteries (TPAs) and in the artery of Percheron (AP). Anatomical presentation of these arteries is of relevant clinical importance for safer neurosurgic...

Introduction: The orbit is a bone cavity in the skull. Its morphological and anthropological knowledge is essential, as it is a region subjected to several surgical procedures. Objective: To analyze the morphology of orbits in the skulls of two populations in Northeastern Brazil Methods: 115 skulls belonging to Federal University of Paraíba (UFPB)...

Introduction: The axis is the second cervical vertebra and differs from the others by presenting particular anatomical landmarks. Morphological variations of the axis in different populations have clinical importance, since the lack of anatomical reference may compromise surgical procedures in this region. Objective: To analyze the morphometry of a...

Introduction: The foramen venosum (FV) is located in the larger wing of the sphenoid bone and allows the passage of emissary veins that help to balance the intra and extracranial pressure. Knowledge of its morphology and associated structures has an important surgical value. Objective: Analyze the morphology of FV and its relation to adjacent foram...

Background Performing surgical procedures around the mitral valve (MV) annulus can cause iatrogenic lesions on the circumflex artery (Cx). The risk of this iatrogenesis comes from the proximity between this vessel and the MV annulus. Objective To evaluate the relation between the MV annulus and the Cx at different spots of its path and highlight t...

Introduction The successful identification of the deceased is vital to the progress of any forensic investigation. This process of identification is facilitated by the determination of age, gender, and ethnicity. One of the main biological traits to be established from skeletal remains is the gender of the individual. In situations in which there a...

Introduction The sternal muscle is an anatomical variation found in the anterior region of the thorax. Objective To report the anatomical characteristics of a new type of sternal muscle. Case Report This was a dissection study in which the sternal muscle found was unilateral and long. Discussion Proximal fixation differs from the classification ado...

Introduction Variations in the formation and in the branching pattern of the brachial plexus are common. Numerous anastomotic variations between the musculocutaneous nerve (MCN) and the median nerve (MN) have been reported and could be implicated in a wide range of sensory and motor dysfunctions. Objective To report an uncommon case of an anastomot...

Introduction: The celiac trunk (CT) is one of the abdominal portion branches of the aortic artery and, together with the superior mesenteric and inferior mesenteric arteries, participates in the abdominal viscera vascularization through a series of anastomoses. Absence of CT or variation in the number of terminal branches implies in varied abdomin...

Introduction Papillae are small conical bumps found on the skin or mucous membranes surfaces. In the mouth, the parotid papillae are responsible for expelling saliva from the parotid gland to its cavity. Sialadenitis is an inflammation that affects the salivary gland and/or its duct. Objectives To report a variable parotid papilla case and its impl...

The piriform aperture is an anatomical structure generally pear-shaped, formed by some facial bones. The knowledge of its morphological presentation is of significant importance for performing a surgical procedure. This study aimed to analyze the morphometry and shape of the piriform aperture in human skulls, considering the sexual dimorphism of th...

Early malnutrition is a risk factor for depression and schizophrenia. Since the offspring of malnourished dams exhibit increased brain levels of serotonin (5‐ HT ), a tryptophan‐derived neurotransmitter involved in the pathophysiology of these mental disorders, it is believed that the deleterious effects of early malnutrition on brain function are...

Several epidemiological and experimental studies have clearly established that maternal malnutrition induces a high risk of developing obesity and related metabolic diseases in the offspring. To determine if altered nutrient sensing might underlie this enhanced disease susceptibility, here we examined the effects of perinatal protein restriction on...

The objective of this study was to analyze the effects of Pressure Controlled Ventilation mode (PCV-C) and PSV mode in diaphragm muscle of rats. Wistar rats (n=18) were randomly assigned to the control group or to receive 6 hours of PCV and PSV. After this period, animals were euthanized and their diaphragms were excised, frozen in liquid nitrogen...

The aim of the study was to analyze the muscle fibers by histochemistry and morphometric methods from patients with Duchenne muscular dystrophy (DMD). Muscle biopsies were taken from the vastus lateralis muscle of five boys between 13 and 15-years of age, with clinical diagnosis of DMD. The histochemistry was performed using myofibrillar ATPases (9...
