Leonardo da Vinci’s anatomical investigations evolved from a focus on artistic training to a rigorous, independent scientific pursuit. His research into the human body progressed from the study of static structures to an analysis of physiological and mechanical activity.1

His investigations included the following systems and organs:

  • Skeletal and Muscular Systems: Early in his career, Leonardo focused on the skeleton and musculature, which he viewed as the essential framework for the human figure.1
  • Internal Organs: As his research deepened, he examined various internal organs, with a particular emphasis on those he considered the "motors" of life and the senses.1
  • Specific Organs: His most profound studies were directed toward the brain, heart, and lungs.1

Leonardo recorded these findings in detailed anatomical drawings, often using transparent layers and cross-sections to accurately visualize the body's interior. These works remain significant achievements in the history of anatomy and scientific illustration.1
