Effect of interprofessional education on cadaver dissection seminar
In this study, we investigated the effect of learning about IPE in cadaver dissection seminars. The seminars were held for 5 days each in 2021 and 2022 (the number of days of participation was arbitrary). In the seminars, teams of 3–5 participants with the same theme collaborated to dissect a single donated cadaver. Teams were made up of participants with different departments: 29 medical students, 12 NP students, and 20 nursing students participated in the seminar, and participants were surveyed before and after the seminars. The Readiness for Interprofessiona l Learning Scale (RIPLS) scores before and after the dissec...

Anatomical study of a human skull with multiple osteomas in a seventeenth-century Dutch still-life painting: bone morphology and artistic intention
This study analyzed a skull with abnormal tumors in a seventeenth-century Dutch still-life painting by a renowned artist, Edwaert Collier (ca. 1642–1708), from anatomical, forensic, and pathologic al perspectives. The morphology of the cranium and teeth indicated that the skull likely belonged to a middle-aged female. We carefully diagnosed the abnormal masses as multiple osteomas on the skull and left femur, based on clinical studies and paleopathological literature, which reported lesions w ith a similar appearance to those observed in Collier’s work. Furthermore, detailed observations of the cranial sutures and epip...

Anomalous drainage of the right gonadal vein
AbstractThe present research aims to present and describe an unusual and rare anatomical variation in relation to the drainage of the right gonadal vein. This anatomical knowledge is crucial as it assists in the work of surgeons and health professionals in general. The dissection occurred in the anterior wall of the abdomen and, through observational analysis, an anatomical variation was found in the drainage of the right gonadal vein in a human cadaver, obtained by anonymous donation, male gender and without predetermined clinical characteristics, ethnicity, and age, belonging to the Padre Albino University Center collect...

Variant formation and branching pattern of superficial palmar arch in a human cadaver: a case report
AbstractSuperficial palmar arch (SPA) is a dominant vascular structure in the palmar region that provides a major blood supply to fingers. Present case describes a rare formation and branching pattern of SPA in a formalin fixed cadaveric left hand. In this case, SPA was formed by the anastomoses between radial artery (RA) and the superficial brachioulnar artery (SBUA), which is defined as an ulnar artery with a high origin in the arm. More interestingly, unlike classic literature, SPA sends out six branches instead of four, and the principle artery of thumb arises directly from SPA instead of RA. The aforementioned variati...

Message to researchers: the characteristic absence of a posterior communicating artery is easily lost in the gerbil
In conclusion, the commercially available MON/Jms/GbsSlc gerbil can easily regain PcomA, and we established a new gerbil strain (MON/Jms/SlcMz) displaying non-PcomA. (Source: Anatomical Science International)

Incidental finding of Clostridium perfringens on human corpses used for the anatomy course
AbstractPost-mortem specimens used for anatomy teaching are commonly embalmed using compositions of chemicals, with the objective to maintain tissue quality and to avoid putrefaction. Monitoring for bacterial or fungal contamination is becoming increasingly important especially when measures are taken to minimize exposure by chemicals such as formaldehyde. In this case, random swabs were taken from six corpses embalmed with ethanol-glycerin and Thiel embalming. Cultures and MALDI-TOF analyses yielded four cases ofClostridium perfringens contamination.C. perfringens is of special interest as a human pathogen. A potential so...

Evolutionary comparative analysis of the extrinsic thoracic limb muscles in three procyonids (Procyon cancrivorus Cuvier, 1798, Nasua nasua Linnaeus, 1766, and Potos flavus Schreber, 1774) based on their attachments and innervation
AbstractThe procyonids (Procyon cancrivorus,Nasua nasua andPotos flavus) are Neotropical carnivorans with the ability to climb trees; however, each one has different locomotor preferences. Thereby,P. flavus is highly arboreal,P. cancrivorus is mainly terrestrial with abilities to swim, andN. nasua is also fossorial. These activities not only require movements of the hands but stabilize the thoracic limb, an action performed by the extrinsic muscles. Besides, former descriptions performed in procyonid species have obsolete terms for these muscles, generating confusion about the comparison among species. Thereby, muscle inne...

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...

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...

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...

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...

The occipital artery: a meta-analysis of its anatomy with clinical correlations
In conclusion, the authors of the present study believe that this is the most accurate and up-to-date meta-analysis regarding the anatomy of the occipital artery. Knowledge about this structure can be of great use when performing revascularization procedures, such as the occipital artery-posterior inferior cerebellar artery bypass, or reconstructive procedures, such as the occipital artery fascial flap.

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.
