INTRODUCTION: The anatomy of the frontal sinus is highly variable and its variations affect the occurrence/course of pathological processes. We investigated its size and relationship to the orbit, searching for patterns that would allow it to be classified anatomically. MATERIAL AND METHODS: Cone beam computed tomography was applied to 91 skulls (age range 21-86 years) to determine sinus height, width, length, and length of contact with the orbit in the coronal and sagittal planes...

INTRODUCTION: Umbilical cord catheters (UCC) are important for the primary care of critically ill newborns. To analyze anatomical variations of the umbilical vein (UV) and its further course, we performed abdominal spiral-CT examinations on stillborns. The aim of the study was to explore the high incidence of mal-positioned UCCs and to improve their positioning. MATERIALS AND METHODS: Eighteen stillborns were investigated (29.2 weeks ± 6.7 weeks (IQR)). CTs were performed using either air or contrast medium injection into the UV...

There is currently no method to quantify the quality of the harvested graft before anterior cruciate ligament (ACL) reconstruction. The purpose of the present study was to explore a method for measuring stiffness of the normal tendon of the semitendinosus muscle using shear wave elastography (SWE). Our investigation comprised two steps. First, we determined orientation of the semitendinosus tendon fibers in 20 lower legs of embalmed cadavers. Second, we investigated the feasibility of quantifying stiffness of the normal semitendinosus tendon by SWE in 24 subjects (48 legs: 24 male and 24 female subjects) in vivo...

Because most malrotations of the small intestine are thought to occur during repackaging, the location of the intestine should vary less during physiological herniation than afterwards. Examination of serial sagittal sections of 27 embryos and fetuses (gestational age six to nine weeks; crown-rump length 15-45 mm) during herniation showed that the jejunum and ascending colon passed through a small opening of the hernia sac at the levels of the stomach and pancreas in 16 specimens. Below the pancreas, a definite mesentery extended between the ascending and descending colon in the abdominal cavity...

Paul E Neumann
Spelling variants are common in Latin anatomical terms. Some of these variants cause confusion with respect to the meaning of the word by altering the base of the word to resemble a different word base. Thus these variants should be considered errors, comparable to errors in declension of nouns and adjectives, and errors in the formation of neologisms. Use of correct Latin words in Latin anatomical terms should increase the rigor, stability and universality of the nomenclature. This article is protected by copyright...

INTRODUCTION: Cutaneous nerves have branches called vascular branches (VBs) that reach arteries. VBs are thought to be involved in arterial constriction, and this is the rationale for periarterial sympathectomy as a treatment option for Raynaud's disease. However, the branching patterns and distribution areas of the VBs remain largely unclear. The aim of the present study was to investigate the anatomical structures of the VBs of the cutaneous nerves. MATERIALS AND METHODS: Forty hands and forearms were examined to assess the branching patterns and distribution areas of the VBs of the superficial branch of the radial nerve (SBRN), the lateral antebrachial cutaneous nerve (LACN), the medial antebrachial cutaneous nerve (MACN), and the palmar cutaneous branch of the ulnar nerve (PCUN)...

Introduction The most effective way to learn human anatomy is through cadaver dissection. Historically, cadaver dissection has been the provenance of professional schools. Increasingly, cadaver-based courses in human anatomy are shifting to the undergraduate level, which creates both problems and opportunities because of differences between undergraduate and graduate student populations. Anxiety associated with dissecting cadavers can create a barrier to learning, and ultimately, entry into the health and medical sciences for some demographic subpopulations of undergraduates...

BACKGROUND: An increase in brain iron is a normal physiological process during brain development but excess accumulation is a risk factor for various neurodegenerative diseases. Thus, knowledge of the normal range of brain iron content is mandatory. The present study was planned to collect normative data on iron deposition in human brains by in vitro analysis. MATERIALS AND METHODS: Iron deposition in basal ganglia was determined by Perl's staining in 31 (18 males, 13 females) non-pathological postmortem brains aged from 18 to 80 years and by inductively coupled plasma mass spectrometry (ICP-MS) in 13 of them (seven males, six females)...

INTRODUCTION: Intraosseous access is a method for providing vascular access in resuscitation of critically ill and injured patients when traditional intravenous access is difficult or impossible. There is a lack of detailed description for the landmark for the insertion point in the literature. The aim of this study was to determine the exact location for intraosseous access. MATERIALS AND METHODS: Radiographic computed tomography (CT) images of a total of 50 dry tibia bones were obtained...

INTRODUCTION: The arterial basket of the conus medullaris is one of several anastomoses between the anterior and posterior spinal arteries. The anatomy of this structure has attracted little attention. This work sought to investigate its configuration in human spinal cords. MATERIALS AND METHODS: Spinal cords from male and female cadavers (n=32) were injected with colored latex through the intercostal, lumbar, medial sacral and the posterior trunks of the hypogastric arteries...

BACKGROUND: PAX6 is a master gene of ocular development and postnatal ocular equilibrium. Congenital aniridia is the hallmark of PAX6 gene haploinsufficiency (Chr. 11 p. 13), but PAX6-associated aniridia is a profound, progressive pan-ocular developmental disorder often leading to blindness. Limbal stem cell insufficiency and corneal findings in PAX6 syndrome: There is congenital visual impairment with advancing loss of vision mainly due to secondary glaucoma and to corneal blindness caused by limbal stem cell insufficiency (LSCI)...

The endoscope is thought to provide an improved exposure of the internal auditory meatus after retrosigmoid craniotomy for microsurgical resection of intrameatal tumors. The aim of this study is to quantify the differences in internal acoustic meatus (IAM) exposure comparing microscopic and endoscopic visualization. A retrosigmoid approach was performed on 5 cadaver heads. A millimeter gauge was introduced into the internal auditory meatus, and examinations with a surgical microscope and 0°, 30° and 70° rigid endoscopes were performed...

James D Pickering, David J H Roberts
Recent changes in anatomy education have seen the introduction of flipped classrooms as a replacement to the traditional didactic lecture. This approach utilizes the increasing availability of digital technology to create learning resources that can be accessed prior to attending class, with face-to-face sessions then becoming more student-centered via discussion, collaborative learning, and problem-solving activities. Although this approach may appear intuitive, this viewpoint commentary presents a counter opinion and highlights a simple alternative that utilizes evidence-based active learning approaches as part of the traditional lecture...

INTRODUCTION: Hysterectomy is the most commonly performed gynecological procedure in the United States with three possible surgical approaches; vaginal, abdominal and laparoscopic. As with any surgical procedure, various anatomical complications can arise. These include injuries to anatomical structures such as the urinary bladder, ureter, intestines, rectum, anus and a multitude of nervous structures. Other complications include sexual dysfunction, vaginal cuff dehiscence and urinary incontinence...

The tensor of the vastus intermedius (TVI) is a newly described component of the extensor apparatus of the knee joint. The objective of this study was to evaluate the appearance of the TVI on magnetic resonance (MR) imaging and its association with the adjacent vastus lateralis (VL) and vastus intermedius (VI) muscles and to compare these findings with the corresponding anatomy. MR images were analyzed from a cadaveric thigh where the TVI, as part of the extensor apparatus of the knee joint, had been dissected...

Since the multi-site closure theory was first proposed in 1991 as explanation for the preferential localizations of neural tube defects, the closure of the neural tube has been debated. Although the multi-site closure theory is much cited in clinical literature, single-site closure is most apparent in literature concerning embryology. Inspired by Victor Hamburgers (1900-2001) statement that "our real teacher has been and still is the embryo, who is, incidentally, the only teacher who is always right", we decided to critically review both theories of neural tube closure...
