M.C.Q. on anatomy of the pelvis udemy course free download

Understand the pelvis anatomy via M.C.Q. involving all its structures and organs

This course entails multiple choice questions in anatomy of pelvis mainly for gynecologists and obstetricians and urologists as well as medical students. It is arranged according to structures and regions of pelvis anatomy. It aims for proper understanding of anatomy of the pelvis especially for surgeons. Here are few examples of these questions but the book is uploaded in bulk upload. Bones and joints
