The anatomy and clinical significance of the sinuvertebral nerve is a topic of considerable interest among anatomists and clinicians, particularly its role in discogenic pain. It has required decades of research to appreciate its role, but not until recently could these studies be compiled to establish a more complete description of its clinical significance. The sinuvertebral nerve is a recurrent nerve that originates from the ventral ramus, re-entering the spinal canal via the intervertebral foramina to innervate multiple meningeal and non-meningeal structures. Its complex anatomy and relationship to discogenic pain have warranted great interest among clinical anatomists owing to its sympathetic contribution to the lumbar spine. Knowledge of the nerve has been used to design a variety of diagnostic and treatment procedures for chronic discogenic pain. This paper reviews the anatomy and clinical aspects of the sinuvertebral nerve.

PURPOSE: Fossa navicularis is a bone defect in the clivus. Familiarity with this anatomical variant is important because it is close to vital anatomical structures in the base of the skull. The aim of this study was to determine the prevalence and morphometric properties of fossa navicularis within the clivus in a Turkish subpopulation using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: A total of 168 CBCT scans (female: 96, male: 71) were evaluated. High-quality CBCT images of patients without a syndromic condition or a history of neurological disease or surgery were included in the study. The prevalence, depth, length, and width of the fossa navicularis were performed. RESULTS: The prevalence of fossa navicularis was 27.5% (n=46 patients). Sex was not associated with the depth, length, or width of the fossa navicularis (P>0.05). A significant positive correlation was found between age and length of the fossa navicularis (P>0.05). CONCLUSION: Fossa navicularis was found to be rare (27.5%). Anatomical variants of the skull base can also be clearly identified on CBCT images. The results of this study may be useful to radiologists, anatomists, and surgeons interested in the skull base.

anatomists to publish their own texts over the years. Such a cascading effect started an ongoing process of refining the text based presentation of anatomical details that eventually led to the emanation of Gray's Anatomy, the masterpiece from Henry Gray. In this review article we have tried to revisit the journey from De humani to Gray's Anatomy and have also highlighted on other anatomical texts that form important landmarks in this journey. The article attempts to focus on the rectification of Galenic errors, description of new discoveries in human anatomy, introduction of the concept of clinical anatomy, emergence of surgical anatomy and the advent of sectional anatomy. The article also put emphasis on the efforts to make anatomical illustrations used in texts more scientific and in tune with the printed matter. We noted with interest that luminary anatomists over the years have contributed in their own individual manner towards the development of text based anatomy and from cumulative perspective their visionary efforts have shaped the outlook of anatomical texts in present times.]]>

The authors have operated the homepage (http://anatomy.co.kr) to provide the learning contents of anatomy. From the homepage, sectioned images, volume models, and surface models—all Visible Korean products—can be downloaded. The realistic images can be interactively manipulated, which will give rise to the interest in anatomy. The various anatomy comics (learning comics, comic strips, plastination comics, etc.) are approachable. Visitors can obtain the regional anatomy book with concise contents, mnemonics, and schematics as well as the simplified dissection manual and the pleasant anatomy essay. Medical students, health allied professional students, and even laypeople are expected to utilize the easy and comforting anatomy contents. It is hoped that other anatomists successively produce and distribute their own informative contents.

Michelangelo was a Renaissance artist showing many works. As the secrets of Michelangelo's art have been revealed recently, various studies have been carried out, revealing the secret code of human anatomy in his work. This was an important clue that Michelangelo dissected a huge number of human beings and was a anatomist with considerable expertise. Brazilian doctors Jalousie Bahaetto and Marcelo G Gli Oliveira, from the Vatican Sistina ceiling murals to the sculpture Pieta, examined the works of the Renaissance genius artist Michelangelo in detail and found anatomical elements in many works. Although some interpretations are controversial, it would be a good experience for medical doctor to appreciate masterpieces of Michelangelo in comparison to their human anatomy.

Because of its embryonic origin, the thyroid gland is predisposed to multiple anatomical variations and developmental anomalies. These include the pyramidal lobe, the origin of levator glandular thyroidae, the absence of the isthmus, ectopic thyroid, accessory thyroid tissues, etc. These anatomical variations are clinically significant to surgeons, anatomists, and researchers. The present study was designed to report anatomical variations and developmental anomalies of the thyroid gland in Ethiopian population. The study was conducted on 40 cadavers used for routine dissection classes. The thyroid gland was exposed and observed for any variations and developmental anomalies. The length, width, and thickness of the lobes were measured using a vernier caliper. Differences in the incidence of pyramidal lobe and absence of the isthmus between sexes were tested using a Pearson chi-square test. The mean length, width, and thickness of the right lobe were 4.24 cm, 1.8 cm, and 1.6 cm, respectively, whereas it was 4.08 cm, 1.8 cm, and 1.6 cm, respectively for that of the left lobe. The pyramidal lobe was noted in 52.5% of the cadavers. The levator glandulae thyroidae were prevalent in 40% of the cadavers. The isthmus mainly overlies the 2nd to 4th tracheal rings and was absent in 7.5% of the cadavers. Accessory thyroid tissue and double pyramidal lobes were noted in 2.5% of the cadavers. Most of the variations of the thyroid gland were seen frequently in female but it was not statically significant. Different clinically important and rare variations of the thyroid gland were found.

The first conference of Korean Association of Anatomists started on November 13, 1948 at the department of anatomy of Seoul National University College of Medicine by about 10 anatomists and staffs from several medical schools in Seoul. It was presented with six lectures at ‘The Second Annual Meeting/First Conference of Joseon Association of Anatomists’.

Although the sternalis muscle has been well known to anatomists, it is quite unfamiliar to clinicians. During routine educational dissection, we came across a well-defined bilateral double sternalis muscle innervated by the intercostal nerve, respectively. The right sternalis muscle 1) became tendinous to insert into the sternum and 2) crossed midline and then intermingled with the left pectoralis major muscle, which could be classified into a double with single cross based on Snosek et al.'s criteria. The left sternalis muscle was composed of two bellies, which were combined at the midway, and became tendinous to insert into the contralateral manubrium, which could be classified into a bicipital diverging with double cross based on Snosek et al.'s criteria. The detailed knowledge on the sternalisis is important for clinicians as well as for anatomists, since the clinical importance of the sternalis muscle has been highlighted in recent years.
