Anatomy MCQs with Answers and Explanations

Human Anatomy is the scientific study of body structures. Some of these structures are very small, and can only be viewed and examined using a microscope. Some larger structures can be readily seen, regulated, measured, and weighed. The word "Anatomy" originates from a Greek root that means "to cut apart." Human Anatomy was first studied by inspecting the surface of the body and observing the wounds and other injuries of the soldiers. Much later, doctors were allowed to look at dead bodies to increase their knowledge.

The components are torn down when a body is dissected to determine its physical attributes and relationships. Dissection is still used in medical schools, Anatomy courses, and labs for pathology. Nevertheless, a variety of imaging techniques have been developed to observe living conditions. These techniques enable clinicians to visualize structures such as a cancerous tumour or a broken bone in the living organism.
