MBBS 1st Year Anatomy Important Questions

Anatomy is the sole of 1st year MBBS and also it’s a vast subject. Most of the students study this subject for the whole year, giving less time for other subjects like Physiology and Biochemistry. But keep in mind that every subjects is important. Sometimes reading this whole thing you may feel exhausted and bored. So how to cope up with this? Remember there is no one in your class who can engulf the whole syllabus and score a good marks. All you have to do is to read the subject in a technical way. That means you have to point out the important topics which are usually coming in previous exams and reading them deeply. And this will generate a good gross concept of anatomy. And not only that, for Anatomy you have to focus on the anatomical images from various good books like Netter’s Anatomy (which I prefer the most). Also let’s take help of the internet. Search images of different body organs and also watch videos from Youtube. All you need is a overall concept of Anatomy and this will make you confident to start reading the 1st line of the chapter.

So the rules you have to follow before start reading anatomy without any stress are here (Must read) :

1. Be confident. Avoid negative influences. Take suggestions from your immediate seniors.
2. Study the previous year question papers and find out important topics. Mark those in your book.
3. Anatomy is a visual science. So look at the pictures, diagrams and practice drawing during reading the particular topic.
4. Always keep a good atlas book (I suggest Netter’s Atlas) beside you. It will help you a lot.
5. Stick to one good book for reading and one atlas for drawing diagrams.
6. After reading the topics discuss with your friends. It will help to memorize the topic.
7. Take help of the google images and Youtube for better understanding.
8. Always try to relate the anatomical names with the region (Like Sternoclavicular joint – It means joint between sternum and clavicle).
9. Few students take help of mnemonics. But I suggest to use mnemonics only for few topics (like brachial plexus). As there are a ton of mnemonics, it will be harder to memorize that too. Try to make your own mnemonics if you want to.
10. Write down point wise and don’t spell wrong (specially for anatomy). It will help you to score good marks.

Here in this post we try to put the Important topics of Anatomy which not only save your valuable times but also give you an idea about the questions ask in the exams. Read all of these followings for short and long questions. Because short notes may come as a long questions. So we don’t divide the topics as short/long questions.
