INTRODUCTION: Safe exposure of the vertebral artery (VA) is needed during resection of tumors close to the artery and during repair of lacerations. We defined the anatomy of the anterior root of each transverse process (TP) from C3 to C6 for identification and exposure of the VA during the anterior approach. MATERIALS AND METHODS: We examined the anatomy of the TP and assessed two approaches for safe identification of the VA, lateral to medial and medial to lateral dissection of the TP, in 20 cadavers...

Exceptions to the anatomical nomenclature rule that names must be in proper Latin include a few terms that contain borrowed Greek adjectives that are not declined like Latin words. Adoption of these adjectives into Latin would change about a half-dozen terms, e.g., vena azyga, vena hemiazyga and fascia darta. The anatomical nomenclature rules apply only to the Latin terms, so there is no requirement to alter the way azygos, hemiazygos and dartos are used in equivalent terms in other languages.

REVIEW
Anthony P Polednak
Systematic reviews (SRs) of anatomical studies may include a meta-analysis (MA) that provides weighted averages as pooled estimates of prevalence. The relationship of the recurrent laryngeal nerve (RLN) to the inferior thyroid artery (ITA) or its branches has been assessed in two published SRs, one without MA of 32 studies (SR1) and the other with MA of 79 studies (SR2). Both SRs reported differences in RLN-ITA patterns (in three categories) by side of the body, but the anterior pattern was less frequent in SR1 vs...

Childbirth can be a traumatic experience on the female body. Some techniques may be implemented to make the process smoother and decrease the potential lacerations that can occur. Episiotomies have been used by obstetricians and midwives to help make the fetal decent down the vaginal canal less turbulent. A physician must use his best judgment on when it is necessary to make this incision and what form of incision to make. Before making an incision one must understand the female external and internal anatomy and thoroughly comprehend the stages of birth to understand how and what complications can occur...

REVIEW

Conjoined twins are suggested to result from aberrant embryogenesis. The two main theories proposed to explain the phenomena are fission and fusion. The incidence rate is 1 in 50,000 births; however, since about 60% of the cases are stillborn, the true incidence is approximated at 1 in 200,000. There is a higher predisposition towards female than male gender with a ratio of 3:1. Conjoined twins are classified based upon the site of attachment. The extent of organ sharing, especially the heart, determines the possibility and prognosis of a separation procedure...

The aim of this study was to investigate the functions of the six subregions of the supraspinatus muscle (SSP) determined by Kim et al. (2007) using real-time tissue elastography (RTE). Twelve young male volunteers participated. The muscular hardness of the SSP was measured at rest and with contraction of the MMT3 in internal, neutral and external rotations. The SSP was functionally divided into five groups on the basis of the RTE results. These functional areas were roughly classified into three property groups: the anterior-superficial, anterior-middle and anterior-deep subregions, which produce contractile force for abduction; the posterior-deep subregion, which produces contractile force for external rotation; and the posterior-superficial and posterior-middle subregions, which maintain tension...

INTRODUCTION: Meralgia paresthetica causes pain in the anterolateral thigh. Most surgical procedures involve nerve transection or decompression. We conducted a cadaveric study to determine the feasibility of lateral femoral cutaneous nerve (LFCN) transposition. MATERIALS AND METHODS: In three cadavers, the LFCN was exposed in the thigh and retroperitoneum. The two layers of the LFCN canal superficial and deep to the nerve were opened. The nerve was then mobilized medially away from the ASIS, by cutting the septum medial to sartorius...

INTRODUCTION: Gross anatomy is considered one of the most important basic science courses in medical education, yet few medical schools require its completion prior to matriculation. The effect of taking anatomy courses before entering medical school on performance in medical gross anatomy has been previously studied with inconsistent results. MATERIALS AND METHODS: The effect of premedical anatomy coursework on performance in medical gross anatomy, overall medical school grade point average (GPA), and Comprehensive Osteopathic Medical Licensing Examination Level 1 (COMLEX 1) score was evaluated in 456 first-year osteopathic medical students along with a survey on its perceived benefits on success in medical gross anatomy course...

OBJECTIVES: The aim of this study was to perform a pioneering investigation into the incidence of pneumatization in human skulls. METHODS: A total of 93 human skulls (≥20 years of age, 69 males, 24 females) were included in the study. The skulls were scanned in a fixed position using cone beam computed tomography (CBCT). The pneumatized space parameters within the nasal septum - width, length, and height - were measured. RESULTS: Two types of finding were identified: (a) Pneumatization, named "sinus septi nasi" (SSN), and (b) "spongy bone" (SB)...

INTRODUCTION: The anatomy of the uterus is defined with the angles of the vagina, cervix and uterine corpus. Hereunder there are angles of version and flexion. The cervical position observed during the vaginal speculum examination, may give information about the uterine anatomy. MATERIAL AND METHODS: In this study, we investigated the place of the cervical position in the estimation of the uterine anatomy observed during the cervical examination. We enrolled 240 patients in our study, who applied to our routine gynecology outpatient clinic with various complaints...

Paul E Neumann
The definition of an organ is vague, so that listing and classifying human organs is problematic. The classical Greek definition of an organ as an instrumental part of the body has been supplemented in modern biology by stating that organs occupy a hierarchical level between systems and tissues. Not all anatomical entities on that level meet the requirement of a special function. Thus it appears that systems are composed of organs and connecting (or linking) structures, such as some connective tissues, various tubular entities and nerves...

OBJECTIVES: We used three-dimensional computerized tomography (3DCT) to obtain images of Eagle Syndrome (ES) cases and measurements of relevant variables. METHODS: Twenty-five subjects with ES and 25 controls were included in this retrospective study. Styloid process length, anterior-posterior styloid process angulation (Sagittal plane angle) (APA), medial-lateral styloid process angulation (Coronal plane angle) (MLA), tonsil-stiloid distance and carotid-stiloid distance were measured on CT and 3DCT images, and cranial and neck angiography was obtained, from a total of 580 images...

Surface landmarks in the neck are important for orientations of cervical glands, arteries, veins, nerves and vertebrae. Recent research suggests some orientations are not correct. What are the cervical landmark orientations in the Chinese population? In this study, two essential cervical anatomy planes, the thyroid cartilage and C7 planes, were assessed in living adult Chinese subjects using computed tomography (CT), and the hyoid, carotid bifurcation, cricoid cartilage, thyroid arteries and vertebral artery were simultaneously positioned...

BACKGROUND: The in-plane lateral to medial approach is a standard technique for ultrasound-guided femoral nerve block (USG-FNB). The first bifurcation of the femoral artery, which consists of the deep artery of the thigh (DAT) or occasionally the lateral circumflex femoral artery (LCFA), is regarded as the distal border for this procedure. We sometimes detect arteries along the estimated needle trajectory for USG-FNB. The superficial (SCIA) and deep (DCIA) circumflex iliac arteries run laterally parallel to the inguinal ligament from the femoral or external iliac artery...

In 1922, Paul Hecker, a French physician and Head of Anatomy at the Medical College of Strasbourg published a sentinel thesis on the ligaments of the craniocervical junction based on a study of comparative anatomy. Unfortunately, this dissertation has been lost to history and until now, was unavailable in the English language. Herein, we present a translation of Hecker's work with an update in its nomenclature, which with modern imaging capabilities of the craniocervical junction is germane and timely. This article is protected by copyright...
