Anatomy is a vast subject. It has so many sub-divisions- gross anatomy, embryology, neuroanatomy, histology etc. But the students have to appear in first professional examination within one year and three months after their class starts. There are hundred medical colleges in our country. But specially in anatomy, adequate teaching staffs are there only in few medical colleges. That's why I have tried my level best for the betterment of the students of all the medical colleges of the country. So that, They can prepare themselves in a spectacular and fantastic way for the examination of anatomy and have a good command over the subject.
