Who wrote "On the Structure of the Human Body" and was known for human dissection?

The correct choice is Andreas Vesalius, who is recognized for his groundbreaking work in human anatomy during the Renaissance. His publication, "On the Structure of the Human Body," also known as "De humani corporis fabrica," was first published in 1543 and is considered one of the major works in the history of medicine. Vesalius challenged longstanding anatomical theories that were largely based on animal dissections, particularly those presented by Galen, who had been the dominant authority on anatomy for over a millennium. By conducting his own dissections of human cadavers, Vesalius provided detailed observations and illustrations that corrected many of Galen's errors and laid the foundation for modern anatomy. His work emphasized the importance of direct observation and empirical evidence in the study of human biology, marking a significant shift in medical understanding.

The other figures mentioned made notable contributions to medicine and anatomy but were not the authors of "On the Structure of the Human Body." William Harvey is known for his discovery of the circulation of blood, Ambroise Paré was a pioneer in surgical techniques and battlefield medicine, and Galen was a prominent physician and philosopher whose work predates Vesalius and influenced medical teaching for centuries, but he did not conduct dissections to the
