The influence of ancient Greek thought on fifteenth century anatomy: Galenic influence and Leonardo da Vinci.

Leonardo da Vinci (1452-1519) can be called one of the earliest contributors to the history of anatomy and, by extension, the study of medicine. He may have even overshadowed Andreas Vesalius (1514-1564), the so-called founder of human anatomy, if his works had been published within his lifetime. While some of the best illustrations of their time, with our modern knowledge of anatomy, it is clear that many of da Vinci's depictions of human anatomy are inaccurate. However, he also made significant discoveries in anatomy and remarkable predictions of facts he could not yet discover with the technology available to him. Additionally, da Vinci was largely influenced by Greek anatomists, as indicated from his ideas about anatomical structure. In this historical review, we describe da Vinci's history, influences, and discoveries in anatomical research and his depictions and errors with regards to the musculoskeletal system, cardiovascular system, nervous system, and other organs.

Francis Sibson (1814-1876): the unsung hero of modern surgery and anesthesia.

Francis Sibson (1814-1876) was a British physician and anatomist widely regarded as a true pioneer of the medical profession. He overcame a tragic and difficult childhood to become an avid educator at several medical schools and dedicated his life to research. For modern scientists, he is most remembered for describing Sibson's fascia, his experimental use of curare in the treatment of hydrophobia and tetanus, and his detailed description of the positions and movements of internal organs. He died on September 7, 1876 at the age of 62 from complications of an aortic aneurysm.
