Variation in the branching pattern of the posterior cord of the brachial plexus is common but variation in the branching pattern of the radial nerve is rare. A rare and unreported variation in the branching pattern of the radial nerve was noted in the left cubital fossa of an embalmed male cadaver during routine gross dissection. After division of radial nerve, the superficial branch enter in the forearm region by piercing between brachioradialis and extensor carpi radialislongus in front of the lateral epicondyle and deep branch goes deep to supinator and wind around head of the radius.However, this present report demonstrates that the radial nerve liesposterior to the lateral epicondyle.The present report can be useful for pain managing therapists as well as surgeons dealing with nerve entrapment or compressive neuropathies and reconstructive surgeries and anaesthetists for ultrasonic pain therapy.

Additional bellies of flexor muscles are commonly reported but presence of supernumerary muscles is an infrequent phenomenon. The present study describes an unusual muscle mass in flexor compartment of forearm simulating pronator teres. During routine dissection the upper limb of a 50 years old male cadaver, a supernumerary muscle was found on left side of the upper limb in the flexor compartment. The origin of the muscle was 2 cm wide and aponeurotic in nature and attached to an oblique line extending from the inferior surface of the medial epicondyle and the medial surface of the trochlea. It was inserted on an oblique line 2.5 cm wide on the radius in area between supinator superiorly and flexor digitorum profundus inferiorly. Existence of accessory muscles, which connect flexor muscles, could be explained embryologically by incomplete cleavage of flexor mass during development. The flexor muscles of the forearm develop from the flexor mass which subsequently divides into two layers: superficial and deep. The deep layer gives rise to flexor digitorum superficialis, flexor digitorum profundus and flexor pollicis longus. These supernumerary muscles are extremely rare entities and probably represent deranged embryological development or the process of atavism in which the anomalous part persist for a longer time in the tree of evolution.

A total of 120 dry bones, 60 each of the right and the left side were included in the study. Distribution of these foramina and tunnels was noted for their number, side, location, course and communication. Their morphometry was done using Vernier's caliper. Incidence of scapular foramina was 7.5% (R > L), whereas scapular tunnels were seen in 15.8% cases. Incidence of the sinuous, curved, and straight tunnels was found to be 50, 39, and 10.7% respectively. Left-sided tunnels were longer than the right ones. Plain and contrast radiographs were taken to confirm the findings. Anatomy literature describes only two scapular foramina, namely, nutrient foramen and suprascapular foramen/notch in a great zeal; occurrence of such anonymous foramina is hardly discussed. Through this study, there is an endeavor towar...

Knowledge of anatomy of liver and its variations is indispensable for accurate diagnosis of cases by radiologists, and prevention of unwanted surgical complications by surgeons. Many researchers have studied the segmental anatomy of the liver, but there are very few studies regarding the surface variations of liver. Aim: To document the surface variations of liver and discuss them from clinical perspective. Materials and Methods: This observational cross-sectional study was conducted from August 2015 to May 2019 on 50 liver specimens in the Department of Anatomy, Vardhman Mahavir Medical College. These livers were observed for any surface variations such as abnormal fissures or lobes, elongation or hypoplasia of lobes, etc. Data were tabulated and stats were calculated in percentages. Descriptive analysis of data has been carried out and mentioned in the study. Results: In the present study, out of 50 liver speci...

This trend stems from the popularity of the online researches and sophisticated software to crosscheck if the written text is ethically correct or not exactly plagiarized. This has culminated into the authenticity and validity of some of the contemporary styles of research being employed to new research methodologies. This paper is a theoretical analysis of the concept and importance of ethical guidelines and the cases of plagiarism. In addition, certain reasons of plagiarizing tendencies have also been dealt with. Conclusions have been drawn from personal experience, related works and university norms to incorporate an ethical code of conduct in the domain of educational research.

Though CT scans are the mainstay of studying the precise fissural anatomy of the lungs, the extra/additional fissures are scarcely reported in gross studies. In the present case we report a supernumerary lobe of a right lung due to presence of a deep fissure seen prominently on its diaphragmatic surface. The fissure was 10.8cm in length, it started from the oblique fissure on the diaphragmatic surface, ran backwards parallel to the inferior border in a curve to cut the posterior border behind and thus creating an additional lobe. This extra lobe could be due to abnormal division of the right principal bronchus. Such unusual fissures and lobes are clinically significant in differentiating broncho-pulmonary segments. Anatomical knowledge of such anomalous fissures and lobes of lungs is also important for surgeons performing segmental resection, lobect...

The knowledge of the morphometry of the subthalamic nucleus is essential for accurate targeting of the nucleus during Deep Brain Stimulation. The present study aims to note the morphometry of the subthalamic nucleus in both the cerebral hemispheres which will prove to be of great value to radiologists and neurosurgeons. A cross‐sectional observational study was conducted in the Departments of Anatomy and Forensic Medicine, Lady Hardinge Medical College & Associated Hospitals, New Delhi on thirty adult cadaveric brain specimens of unclaimed and donated corpses. The specimens were categorized into 3 age groups: 20-35, 35-50 and above 50 years. All samples were collected after following the standard protocol for ethical clearance. The morphometric study of 60 subthalamic nucleus were thus conducted. Transverse section of the brain was made at a plane 4mm ventral to the plane containing mid commissural poi...

Both developed and developing countries are the beneficiaries of the new scientific knowledge and its application. Advanced knowledge and the ethical issues are inseparable from research, treatment, prophylaxis and prevention involving human diseases. It is necessary to make well informed decisions about acceptance of advancements that have taken place elsewhere and also prepare systems for our research and medical education. Bioethics therefore needs to be grounded in the local socio cultural context and health care systems. Students make first contact with human biological tissue in the Anatomy department. The seeds of ethical practices and professionalism are sown here. Therefore appropriate knowledge and attitudes of anatomists and cell biologists towards human tissue is important for regular practice of medicine. A questionnaire based study of knowledge and attitudes of 300 anatomy faculty related to use of human biological materials in research and education was conducted. The items included in the questionnaire were to judge the awareness about the same i.e., laboratory handling of human material and research related to corpses, organ & whole body donation along with their use in clinical learning and research in various medical specialties like, orthopedics, surgery, ENT, anesthesia etc. for clinicians, physicians and surgeons as well as undergraduate, post graduate and allied workforce teaching. The data collected from the respondents in the form of positive and negative responses was analyzed. The study identifies the knowledge gaps and the perceptions of faculty regarding the scope and utility of understanding the role of human biological tissues in curriculum and research and transmission of message to the next generation of learners.
