Department

The Department of Forensic Medicine and Toxicology imparts undergraduate teaching to MBBS students in accordance with the CBME curriculum across Phase II and Phase III. Teaching is delivered through a structured blend of didactic lectures, small-group teaching, self-directed learning, student seminars, and regular assignments, ensuring both conceptual clarity and clinical relevance.


The department places strong emphasis on competency-based learning and medico-legal skill development. Lecture sessions are designed to cover the theoretical foundations of forensic medicine, medical jurisprudence, and toxicology, while practical sessions focus on hands-on training in the preparation, completion, and interpretation of medico-legal documents and certificates. These include wound certificates, age estimation reports, drunkenness examination forms, medico-legal examination of the foetus, sexual offence examination documentation, viscera packing procedures, and interpretation of post-mortem certificates.


Students are also trained to recognize the medico-legal importance of bones, weapons, poisons, plant specimens, and other materials commonly encountered in forensic practice. OSPE-based training is integrated into practical teaching, and practical records are evaluated systematically, with record marks contributing to internal assessment.
