Kazimierz Telesfor Kostanecki (1863-1940) remains one of the most important figures in the history of Polish medicine and natural science. He was the creator of one of the biggest scientific schools on Polish soil, a researcher versatile, working in parallel on many fields of natural science exploration. In his view, anatomy has become a dynamic and comprehensive science, that combines what today belongs to histology, cytology and embryology. Kostanecki has created an universal model of research, referring to comparative methods and based on planned series of experimental studies, especially when it came to issues related to developmental anatomy and mechanics of fertilization. This model was used and developed by his students and followers. It is not surprising, therefore, that the name Kostanecki has been repeatedly reported in the world literature, and a number of phenomena and facts established by him has kept its value, which comes obviouswhen we still can find citations of Polish scholar works in the contemporary monographs and articles.

We report a case of a male cadaver aged 72 years with an ectopic location of the papilla of Vater. The ectopic papilla was situated at the supero-posterior border of the 3rd portion of the duodenum at a distance of 0.9 cm from the limit of the 2nd and 3rd portions of the duodenum. The frequency of this anomaly fluctuates between 0 and 11.83% and when the papilla is located distal to its usual position the usual location is in the proximal 2 cm of the 3rd part of the duodenum. We refer to the possible difference in the papilla’s location between patients and cadavers and call attention to the differential diagnosis with spontaneous or surgical fistulae.

Introduction and aim. Cadaveric dissection is the mainstay of learning anatomy by medical students. Even though newer teaching learning methodologies have been implemented to facilitate learning anatomy, cadaveric dissection remains the most preferred method by students. The objective of this study was to analyze the student perspective of different aspects of learning anatomy with their positive and negative experiences and to get a better understanding of their opinions and their experience. Material and methods. In this cross-sectional study, a pretested and validated questionnaire was used to collect information from the students after approval from the Institutional Ethics Committee. Informed consent was obtained from every student prior to their participation in the study. Results. Three hundred seventy-seven students took part in this study and the response rate obtained was 63.5%. The majority of the students stated that cadaveric dissection has helped them in learning basic anatomy and had deepened their understanding of complexity of human body and has helped in better performance in clinical applications. The smell of formaldehyde and eye irritation was cited as the major reasons for finding dissection sessions challenging. Most of the students agreed that counselling before dissection sessions will help to alleviate the emotional reactions to cadavers. Conclusion. The students unanimously agreed that cadaveric dissection sessions are the best way to learn basic anatomy complemented with newer teaching tools like prosection and computer-based approaches. However, the problems encountered by the students like smell and irritation of formaldehyde need to be addressed with usage of alternative techniques.

This study introduces an anatomical basis for surgeries such as thoracoscopeassisted thoracolumbar spinal anterior interbody fusion in terms of image observing and corpse specimen anatomising. The observation of the 3-dimensional computed tomography (CT) image indicates that segmental arteries are visible and run in the central supersulcus of the corresponding vertebral body’s side, while the branches are invisible. The distances between adjacent segmental arteries in T₁₀/₁₁, T₁₁/₁₂, T₁₂ /L₁, L₁/₂,, and L₂/₃ are 23.35 ± 1.48, 25.61 ± 2.08, 29.12 ± 2.30, 32.53 ± 2.18, and 33.73 ± 2.29 (mm), respectively. And the observation by the thoracolumbar spine side of the adult corpse specimens shows that segmental arteries and veins constantly exist and run in the central supersulcus of the corresponding vertebral body’s side; each segmental artery has some small branches; the zone between the upper and lower segmental arteries form a relatively non-vascular nerve safe zone, where the intervertebral space (disc) locates. The distances between adjacent segmental arteries in T₁₀/₁₁, T₁₁/₁₂, T₁₂ /L₁,L₁/₂,L₂/₃ are 23.34 ± 0.78, 25.54 ± 0.85, 29.11 ± 1.01, 32.82 ± 1.28, and 33.71 ± 1.42 (mm), respectively. The safe zone, with the intervertebral disc as the reference mark, can provide enough operation space for surgeries like thoracoscope-assisted anterior interbody fusion and reducing damage to blood vessels as well as surgical complications. Additionally, the arrangement and distribution of segmental arteries can be clearly displayed on the 3-dimensional CT image and the result is basically consistent with that of corpse specimens. Therefore, the 3-dimensional CT image can be regarded as the reference for video-assisted thoracoscopic surgery plans. (Folia Morphol 2010; 69, 3: 128–133)

Needless to say, medical topics have always aroused a great interest among various artists. What is more, a great number of art works has been preserved, which undoubtedly contributes to the enrichment of our knowledge about doctors working in the previous centuries. Moreover, in the Renaissance, one could easily notice the thriving development of paintings, presenting ordinary scenes from everyday life, which was started mainly by the Dutch. Furthermore, among frequent topics undertaken by famous artists we can diff erentiate the ones that presented surgeries and autopsies. In the given article we will discuss the paintings presenting the anatomy lessons by Pietersz, Pickenoy, van Mierveld, Rembrandt, and van Neck, since the analysis of given works provides a great source of information about the doctors living in these times.

Od wielu stuleci malarze interesowali się tematyką medyczną. Do naszych czasów zachowało się wiele dzieł sztuki, które wzbogacają naszą wiedzę o lekarzach z minionych wieków. W epoce renesansu rozpoczął się bujny rozkwit malarstwa rodzajowego, który zapoczątkowali Holendrzy. Do częstych tematów malarskich sławnych mistrzów należały m.in. sceny rodzajowe przedstawiające zabiegi chirurgiczne czy sekcje. W pracy zostały omówione obrazy przedstawiające lekcje anatomii Pietersza, Pickenoya, van Miervelda, Rembrandta, van Necka. Analizując te dzieła wiele możemy się dowiedzieć o żyjących wówczas lekarzach.

Introduction. Although there are lots of varieties of aorta arch, they seem to appear relatively rarely. Anomalies of aortic arch departures are mainly concerned with its location, course, the place of departure and number of its main branches. However, they warrant attention due to their importance in operative, diagnostic, and endovascular procedures. Aim. We want to present here a case of a female cadaver with rare aortic arch origin of the left vertebral artery. The aim of this article is to complete the frame of anomalies in aortic arch and to explore rare variability shown in this specific case. Description of the case. The present report describes an anomalous case of the left vertebral artery arising from the aortic arch between the left common carotid artery and the left subclavian artery in a female cadaver during dissection in an anatomical laboratory. Aortic origin of the vertebral artery is a rare anatomic variant. Conclusion. Thorough knowledge of anomalous origin is important for patients who undergo operation of an aortic arch or inferior part of the neck. Normally, the vertebral artery arises from the first part of the subclavian artery on both sides.

This article explains and shows some examples of the graphical and sculptural works of the Austrian pathologist Veit Krenn, who uses his detailed knowledge of microscopic and macroscopic anatomy to create derived objects of art, which strikingly transcend the templates to reach an impressive state of abstraction – appealing discoveries of the true contents of the original forms towards their structural essence. By means of analogies the creative approach of the artist is readily used to illuminate similar ways of contemplating the essence of meaning in the philosophy of language in a brief outline

The tympanic sinus is one of the most important structures of the human temporal bone. Located in its vicinity are the round window, posterior semicircular canal and facial nerve. The study was performed on 30 temporal bones taken from adult cadavers of both sexes. After the tympanic sinus had been identified, its morphological features were evaluated. The sinus was then measured using a graticule with an accuracy of 0.05 mm. Also measured were the shortest distances from the tympanic sinus to the neighbouring structures (the lateral and posterior semicircular canal, the facial nerve canal and the jugular fossa). The measurements were performed under a surgical microscope with eye-piece graduation of 0.05 mm accuracy. Four main morphological types of fossa of the tympanic sinus and two main developmental forms, a deep sinus and a shallow sinus, were distinguished. The existence of a deep sinus was associated with absence of the bridge and the sinus was shallower when the bridge was prominent. The very deep sinuses were located close to the facial canal, in some cases penetrating deep in its vicinity (in some cases even going beyond two thirds of the canal’s circumference), which poses a real risk of facial nerve damage during surgical removal of a lesion located in close proximity to the nerve. In most cases the tympanic sinus is elliptical in shape and its long diameter lies in the vertical plane (mean value: 2.73 × 2.23 mm). The mean distances from the tympanic sinus to the facial nerve canal, lateral semicircular canal, posterior semicircular canal and jugular fossa were 1.5 mm, 2.1 mm, 1.59 mm and 5.5 mm respectively. No correlation was observed between the measurement results and either sex or side.

The studies were carried out on the claustrum of 8 adult rabbits. Four types of neurons were distinguished: 1. Multipolar neurons, which have dendritic trunks either with conus (multipolar polygonal perikarya) or without conus (multipolar rounded perikarya). Both subdivisions of the multipolar neurons have 3–6 dendritic trunks. Only some branches of these trunks have spines. An axon emerges mainly from the cell body, rarely from the initial part of the dendritic trunk. 2. Bipolar neurons with fusiform or rounded perikarya; they have two dendrites covered with spines. An axon originates directly from the cell body or from one of the dendritic trunks. 3. Triangular neurons, which have three dendritic branches with spines. An axon emerges directly from the soma, often near the primary dendritic trunk. 4. Pear-shaped neurons with one or two dendritic trunks arise from one pole of the cell body and with an axon that originates from the opposite side of the perikaryon. The dendrites are covered with spines.

The persistent sciatic artery (PSA) is a rare anatomical variant where the internal iliac artery and the axial artery of the embryo provide the major supply of the lower limb, the superficial femoral artery being usually poorly developed or absent. We describe an extremely large right PSA in a 79-year-old male cadaver during a medical gross anatomy course, with simultaneous existence of a hypoplastic superficial and deep femoral artery. The PSA, which was a continuation of the anterior division of the right internal iliac artery, entered the buttock through the greater sciatic foramen situated in the gluteal region laterally to the sciatic nerve and in the mid thigh medially to the same nerve, becoming in the popliteal fossa the popliteal artery. Neither the superficial nor the deep femoral artery had communication with the popliteal artery. Because the PSA in our study was the only blood supply to the lower limb, we present the embryologic origins and the clinical anatomy of this artery.

Neurosurgical procedures in the region of the petroclival region of the skull base require unique knowledge of the local anatomy. The measurements of this region considering the visible anatomical landmarks are helpful both during surgery and while planning the general schemes for the approach. We have evaluated the anatomy of the anterior surface of the petrous bone and of the middle fossa taking into consideration the surgical removal of part of the petrous bone — the anterior petrosectomy. We have measured the distances and angles between the chosen structures in this region. The measurements were taken on 10 skulls, on both sides. The results enrich the algorithm of the anterior petrosectomy.

Despite intensive anatomical research during the last century, anatomical structures or variations of these structures may still cause confusion or even iatrogenic injury. A matter of debate is the sternalis muscle. We present a review of the literature of the sternalis muscle with special emphasis on its clinical anatomy.
