I am grateful to Almighty for giving me the opportunity to edit these three volumes, and further for sustaining the interest which many a times did oscillate. When I met Mr YN Arjuna, Publishing Director in CBS, in May 2003, light was seen at the end of the tunnel and it was felt that the work on the volumes could begin with definite schedule. He took great interest in going through the manuscript, correcting, modifying and improving wherever necessary. He inducted me to write an introductory paragraph, brief outlinesof embryology and histology to make it a concise and complete textbook. Having retired from Lady Hardinge Medical College within a fortnight of getting this assignment and having joined Santosh Medical College, Ghaziabad, my colleagues there really helped me. I am obliged to Prof. Varsha Katira, Prof.Vishram Singh, Dr Poonam Kharb, Dr Tripta Bhagat (MS Surgery), Dr Nisha Kaul and Ms Jaya. They even did dissection with the steps written for the new edition and modified the text wherever necessary. From 2000-03, while working at Subharti Medical College, Meerut, the editing of the text continued. DrSatyam Khare, Associate Professor, suggested me to write the full course of nerves, ganglia, multiple choice questions, etc. with a view to revise the important topics quickly. So, appendices have come up at the end of each section. I am grateful to Prof. AKAsthana, Dr AKGarg and Dr Archana Sharma for helping me when required. The good wishes of Prof. Mohini Kaul and Prof. Indira Bahl who retired from Maulana Azad Medical College; Director-Prof. Rewa Choudhry, Prof. Smita Kakar, Prof. Anita Tuli, Prof. Shashi Raheja of Lady Hardinge Medical College; Director-Prof. Vijay Kapoor, Director-Prof. JM Kaul, Director-Prof. Shipra Paul, Prof. RK Suri and Prof. Neelam Vasudeva of Maulana Azad Medical College; Prof. Gayatri Rath of Vardhman Mahavir Medical College; Prof. Ram Prakash, Prof. Veena Bharihoke, Prof. Kamlesh Khatri, Prof. Jogesh Khanna, Prof. Mahindra Nagar, Prof. Santosh Sanghari of University College of Medical Sciences; Prof. Kiran Kucheria, Prof. Rani Kumar, Prof. Shashi Wadhwa, Prof. Usha Sabherwal, and Prof. Raj Mehra of All India Institute of Medical Sciences and all my colleagues who have helped me sail through the dilemma.
