Legal Frameworks Upholding Deceased Individuals' Rights and Enabling the Use of Cadavers in Anatomy Education and Research: A Systematic Review.

The study of human cadavers is essential for teaching, advanced training, and research in medical and anatomical sciences. Medical institutions around the globe presently face a scarcity of cadaver supplies. For the majority of countries, unclaimed bodies are still the primary source of cadavers despite guidelines issued by the International Federation of Associations of Anatomists, which discourage the use of unclaimed bodies.

Artery of Percheron, an Uncommon Variant of Posterior Cerebral Circulation: A Case Report.

The posterior communicating artery (PcomA), P1 and P2 segments of the posterior cerebral arteries (PCAs) give rise to numerous small branches that chiefly supply the thalamus and midbrain. Thalamic vascular supply is classically categorized into four regions: anterior, paramedian, infero-lateral and posterior. Despite significant variations and overlap in the blood supply, this traditional classification helps in understanding the vascular anatomy of the thalamus.
