Selections of the proximal-distal axis were removed so as to produce wings lacking entire skeletal levels. The innervation of the resulting limb from the appropriate spinal nerves was tested by electrophysiological recording, gross dissection and serial sections. Ther nerves form repeatable and ordered patterns in the modified limbs which can be readily related to the normal pattern. In general...

In their excellent quantitative analysis of students’ valuation of gross anatomy as an ‘‘important’’ course, Böckers et al. (2010) come to the conclusion that this high valuation could depend on the students’ perceived growth in professional competencies during the course. The students counted among these competencies their increased abilities in teamwork, time management, learning strategies, ...

BACKGROUND Formaldehyde is extensively used for preservation of cadavers in departments of anatomy. However, it is a noxious chemical which may cause serious health problems. OBJECTIVE To assess the effect of exposure of medical students to formaldehyde at the Department of Anatomy, Niger Delta University, Nigeria. METHODS In a questionnaire-based study, 93 second-year medical students were...

The present study was designed to determine the extent of lymph node dissection for clinical T1 non-small cell lung cancer without negatively influencing curability. The study included 192 cases with clinical T1 non-small cell lung cancers who underwent lobectomy with mediastinal lymphadenectomy. Among 69 cases with right upper lobe tumors, metastasis was found in subcarinal lymph node in one c...

The concept of body donation has evolved over centuries and there are still considerable discrepancies among countries regarding the means by which human bodies can be acquired and used for education and research. In many countries the act of body donation is guided by laws and ethical frameworks. This has evolved alongside the needs for medical knowledge and for improved teaching of human anat...

Introduction During routine dissection in the gross anatomy course, the author was called to confirm the absence of the right extensor digitorum longus (EDL) muscle in a 49-year-old Caucasian male who died of pneumonia. Once confirmed, the author also noted the left foot had only a single EDL tendon to the fifth toe. Further dissection by the author revealed other tendon variations. During the ...

Computed tomographic (CT) colonography is a promising noninvasive examination for colorectal cancer screening; however, the optimal interpretation strategy remains undecided. Virtual dissection is an innovative technique whereby the three-dimensional (3D) model of the colon is virtually unrolled, sliced open, and displayed as a flat 3D rendering of the mucosal surface, similar to a gross pathol...

Gross dissection has a long history as a tool for the study of human or animal soft- and hard-tissue anatomy. However, apart from being a time-consuming and invasive method, dissection is often unsuitable for very small specimens and often cannot capture spatial relationships of the individual soft-tissue structures. The handful of comprehensive studies on avian anatomy using traditional dissec...

stanford type a acute aortic dissection (aad) is a very rare complication, with potentially lethal consequences in pregnancy. in fact, pregnancy has been regularly associated with the possibility of aortic. dissection in almost half of young women. herein, we present the case of a 38-year-old woman in her 37th week of pregnancy. the patient’s medical history was indicative of g4l2ab1(4 gestaiti...

Formaldehyde (FA) is an aldehyde used in antiseptics and adhesives. The World Health Organization (WHO) and other institutes have linked FA to sick building syndrome and allergic diseases. Recent studies have reported that cadavers embalmed using formalin and ethanol-based preservative solutions release FA vapor during dissection and that FA vapor may adversely affect students and lecturers in ...
