Background: Anatomy Act provides legal ambit to medical educationists for the acquisition of cadavers. The changing medical education scenario, socio-demographic change, and ethical concerns have necessitated an urgent review of its legal and ethical framework. Suitable amendments addressing the current disparities and deficiencies are long overdue. Methods: Anatomy Act in India is a state Act, which ensures the provision of human bodies for medical education and research. The methodology included three components namely: Comparison of various Anatomy Acts clause by clause, Feedback from anatomists, and Formulation of comprehensive model Anatomy Act. Results: Various Acts studied showed discrepancies in the purpose of the Act, roles and duties of stakeholders, regulation for body donation, the procedure to handle unclaimed bodies, disposal of dissected bodies, etc. No Act defines a donor and neither addresses the issue of transport of anatomical material. Only ten states have a clause for body donation. Acts of only six states have been amended over the last 50 years. Three states denied having an Act. The whole exercise of review of Acts, extensive feedback received from end-users, and taking into account global good practices, culminated in drafting a comprehensive model Anatomy Act founded on ethical principles. Conclusion: India, with the largest number of medical colleges, is not only at the forefront but also a hub of medical education in the Southeast Asia region. Legal reform can be a torchbearer to promote ethical and transparent practices for obtaining cadavers for other countries of the region with similar socio-demography and shall also motivate anatomic fraternity across the globe for critical analysis of their respective Anatomy Acts.

During the strengthening and weakening procedures of intraocular muscles, distance of insertion from the sclerocorneal junction is an important determinant in the identification of muscles. During repositioning of the aponeurosis of the muscles, it is desired that the width should not change in order to avoid diversion of forces. Available anatomic studies on insertions of extraocular muscles are few, date back to early twentieth century and have been conducted on mostly white population. The present study is an attempt to document the insertions of recti and oblique muscles in Indian population. Forty eyeballs were removed from orbit. Insertion of recti and obliqui were cleaned and eyeballs were perfused with normal saline to regain the volume (hence shape and size) before recording observations. Insertion of recti and obliqui muscles were observed under various study parameters. The distance of insertion of recti from the limbus were found to be 7.3 mm, 8.06 mm, 8.71 mm, and 8.74 mm for medial, inferior, lateral, and superior rectus, respectively. The superior oblique was aponeurotic and found to be more variable in mode of insertion as compared to inferior oblique which had a fleshy and relatively constant insertion. The observations on insertion of recti and obliqui as obtained in present study differ from earlier studies to the tune of 1-1.5 mm. This may be attributed to adoption of method of reperfusion of eyeball before recording observations thus maintaining size close to in vivo. The observations are expected to be closer to actual.

The peroneus quartus (PQ) is an accessory muscle of the peroneal/lateral compartment of the leg. The muscle has often been implicated as a cause of pain in the lateral ankle region, and subluxation or attrition of the peroneal tendons. The present study was aimed at observing the prevalence and morphology of this muscle in human cadavers. Ninety-two embalmed lower limbs were dissected for this study. The PQ muscle was found in 21% of the limbs. In all these limbs it originated from the lower part of the lateral surface of the fibula, the undersurface of peroneus brevis and the posterior intermuscular septum. In the majority of limbs, insertion was on the retrotrochlear eminence of the calcaneus. Taking into account the possibility of this muscle being a cause of lateral ankle pathology, the present study attempts to correlate the findings with the anatomy of the surrounding region. The frequent occurrence of this muscle in humans is suggestive of a progressive evolutionary change to evert the foot in order to assume a bipedal gait.

Advancement in imaging techniques and interventional cardiology procedures have generated renewed interest in anatomy of tricuspid valve complex. The purpose of the present study was to characterize the morphology of tricuspid valve leaflets using objective criteria. Thirty-six embalmed cadaveric hearts were utilized for the present study. Leaflet morphology was studied using newly defined criteria. Commissural zones were identified and leaflets were delineated. Presence of scallops was also recorded. Single leaflet was observed in six cases, double in 26 cases, and triple in four cases. The anterior leaflet is large with multiple scallops and frequently accrues portion of inferior leaflet. The septal leaflet is in the form of a plateau and also frequently accrues parts of inferior leaflet. The inferior leaflet rarely occurs as independent leaflet. A wide un-indented basal zone exists across the valve leaflets. The study found that the tricuspid valve is rarely tricuspid. It also generated the hypotheses that the tricuspid valve does not open completely due to presence of a wide basal zone and the valve does not close completely owing to incongruence and lack of coaptation of leaflets. The findings provide clear understanding of leaflet morphology of tricuspid valve. This will help imaging specialists for interpretation of images and cardiologists for interventional procedures. The findings also enhance our understanding of pathophysiology of conditions like functional tricuspid regurgitation.
