The red ruffed lemur, Varecia rubra ( É. Geoffroy Saint-Hilaire, 1812): a comparative morphology investigation of lingual papillae and connective tissue cores
AbstractThe morphology of the lingual papillae (filiform, foliate, fungiform, and vallate papillae) and the underlying connective tissue core of the red ruffed lemur (Varecia rubra) of a strepsirrhines species were studied using light and scanning electron microscopy. The filiform papillae distributed at the root of the tongue were larger than the structures distributed at the body and apex. Six to eight vallate papillae were arranged in a Y-shape at the border between the lingual body and the lingual root. Foliate papillae were observed at the posterior lateral border of the tongue. Scanning electron microscopy revealed a...

Anogenital distance and anal position index in cadaveric human fetuses
AbstractThe aim of this study is to contribute to the determination of the normal values of human anogenital distance (AGD) and anal position index (API) in the antenatal period. 59 formalin-fixed human fetuses were examined. AGD was measured by the distance between the center of the anus and the posterior fourchette in females, and the distance between the center of the anus and the posterior scrotal raphe in males. API in female fetuses was determined with the formula API = fourchette–center of anus/fourchette-coccyx formula, and API = posterior scrotal raphe-center of anus/posterior scrotal raphe-coccyx in ma...

The thyrocervical trunk: an analysis of its morphology and variations
In this study, the variety of the branching and morphology of the TT was presented, proposing its novel classification based on the five most commonly prevalent types. Types 1 and 2 were the most common, with a prevalence of 26.8% each. This work also provides physicians with crucial data about the mo rphology of the TT and its branches, which can surely be of use when performing endovascular or reconstructive procedures in the cervical region.

Development of a new histological identification method of human sinoatrial node suitable for immunohistochemical study
AbstractHistological identification of the human sinoatrial node (SAN) remains a challenge. Conventional identification methods, such as Lev ’s method, have certain limitations. The aim of our study was to develop a new histological identification method that could properly identify the sinoatrial node, applicable to the immunohistochemical study of intra-nodal structures. Thirty-nine human autopsied hearts were included in this study. The cases included 23 men and 16 women ranging in age from 20 to 99 years. The sinoatrial area from eight control samples was cut in the vertical section using the conventional Lev’s me...

An evaluation of mandibular canal variations: a systematic review and meta-analysis
AbstractThe inferior alveolar nerve and vessels are carried via the mandibular canal, which extends bilaterally from the inferior alveolar foramen to the mental foramen. Bifid and trifid mandibular canals result from abnormal fusions of nerve canals. The purpose of this study was to provide an up-to-date and comprehensive analysis of the prevalence of mandibular canal variations among healthy adults, and to identify any potential ethnic, sex, or laterality predilections. The pre valence of the bifid mandibular canal was 18.87% and that of the trifid canal 1.3%. Unilateral variants were three times commoner than bilater...

Morphometric and morphological evaluation of temporozygomatic suture anatomy in dry adult human skulls
This study aims to evaluate the position, morphometric, and morphological features of the temporozygomatic suture (TZS) located on the zygomatic arch (ZA) in dry adult human skulls. Thirty-two crania were evaluated. Measurements for the TZS were carried out using the ImageJ software. Morphometric measurements were carried out bilaterally in 23 crania and unilaterally in 9 crania (right: 4, left: 5). A total of 55 TZSs were analyzed. Localization of the TZS was determined according to the reference landmarks on the ZA. Morphologic features of the TZS evaluated in terms of “joint shape type” and “suture margin pattern...

Morphometric evaluation and classification of the superior orbital fissure on 3D MDCT images
AbstractThe anatomy of the superior orbital fissure is very important because of the spaces it connects, the regions it is adjacent to, and the structures it contains. We aimed to study the width, length and types of the structure, their change according to gender, body sides, and age. The fissure shape has many variations that are not easy to systematize. Therefore, it was aimed to classify them with various reference points determined for the first time, identify their types and determine their incidence. An objective and comprehensive classification was used on 3-dimensional images using multidetector computed tomograph...

Relationship between the nasal profile and craniofacial structures: does part of the nasal profile reflect some craniofacial structures?
This study aims to evaluate the relationship between the nasal profile and other craniofacial structures. Lateral cephalometric images of 124 adults were collected for this purpose. Statistical analyses such as regression analysis and canonical correlation analysis (CCA) were conducted on nasal and craniofacial anatomical parameters and their relationships. The regression analysis revealed that nasal length was related to maxillary height; nasal depth was related to the position of the maxilla and anterior cranial base length; and nasal base angle was related to upper dentoalveolar height. CCA revealed that nasal parameter...

A review of anatomical terminology for the hip bone
This study explores the variation in terminology for the hip bone through a literature review. In total, ten terms used to describe the hip bone were searched in PubMed, JSTOR, and EBSCO databases: “coxal bone,” “hip bone,” “innominate bone,” “os coxa, ” “os coxae, ” “ossa coxa, ” “ossa coxae, ” “os innominatum, ” “os pelvicum, ” and “pelvic bone.” Results found that the terms “hip bone” and “pelvic bone” were the most commonly used terms, with the most frequently used discipline being medicine. However, we argue against the use of these terms in favor of “coxal bone” or ...

Atavistic and vestigial anatomical structures in the head, neck, and spine: an overview
AbstractOrganisms may retain nonfunctional anatomical features as a consequence of evolutionary natural selection. Resultant atavistic and vestigial anatomical structures have long been a source of perplexity. Atavism is when an ancestral trait reappears after loss through an evolutionary change in previous generations, whereas vestigial structures are remnants that are largely or entirely functionless relative to their original roles. While physicians are cognizant of their existence, atavistic and vestigial structures are rarely emphasized in anatomical curricula and can, therefore, be puzzling when discovered incidental...
