Question
Anatomy and Physiology Through the Ages
What does the heart do? It pumps blood, of course. So many of us learn this fact at an early age that it is considered common knowledge. But if you asked someone in ancient Greece that question, they may have told you that your heart controls your thoughts! Ancient people believed the heart was the center of intelligence and that it also controlled your feelings and body movement.
So how did we get to where we are today? The knowledge about our bodies that we take for granted was gained through adversity, struggle, and even some literal blood, sweat, and tears. Let’s explore the work of civilizations throughout history to understand the human body:
Thousands of years before the Common Era, ancient civilizations in Egypt and China were curious about the human body. They learned mostly by examining animals and, in some cases, human bodies as well. Ancient civilizations believed sickness came from imbalances in the body, but at the time, they did not have the methods or the evidence to prove their ideas. They used natural remedies such as herbs, plants, and minerals to heal.
The ancient Greeks were the first big contributors to our understanding of anatomy. Around 400 BCE, Hippocrates began observing patients and recording symptoms to better understand diseases, and he became known as the father of medicine. Around 300 BCE, Herophilus, another famous Greek, performed detailed dissections on humans and gained groundbreaking knowledge about organs and their functions.
Later, a Roman physician named Galen (born in 129 CE) built upon this knowledge. His work with anatomy was based mostly on apes and pigs since dissecting human bodies was highly restricted at that time. Galen also treated wounded gladiators after battles; this work with bleeding gladiators helped him understand more about anatomy, including the discovery that arteries contain blood. Up until that point, people thought that arteries contained air! Galen's ideas influenced medicine for centuries.
During the Middle Ages, the study of anatomy slowed down. The early Christian church in Europe restricted the dissection of human bodies for the study of medicine, and since disease was often seen as a punishment for sin, great effort was not put into treating illness. This time is regarded as a dark period in medicine because little progress was made in our understanding of the body and its healing. However, in the Muslim empire at this time, great strides were made in chemistry that paved the way for future medical progress.
It wasn't until the Renaissance, around the 15th century, that the study of anatomy accelerated again. Andreas Vesalius, known as the father of modern anatomy, started dissecting human bodies to understand them better. The artist Leonardo da Vinci also performed dissections to create sketches showing various parts of the human body. He made numerous sketches including of the eye, brain, muscular structure, and even a detailed drawing of an unborn baby in the womb.
The development of the microscope in the 16th century allowed scientists to see beyond what was visible to the naked eye. Then, in the 19th and 20th centuries, even bigger advancements were made as scientists discovered germs, which led to an understanding of how infections spread. This discovery helped in the development of vaccines and antibiotics, revolutionizing medicine by helping us fight infections more effectively.
Thanks to advancing technologies, scientists now have access to imaging devices such as PET and CAT scanners and magnetic resonance imaging (MRI) that would be unimaginable to scientists like Galen and Vesalius. This technology allows physicians and scientists to have a glimpse of what is inside the body without performing surgery. Our understanding of physiology helps us to treat disease more effectively than ever, and the body of knowledge continues to grow.
1. How have the methods that humans use to study anatomy and physiology changed over the past 2,000 years? Which historical period in the study of A&P do you find most interesting, and which tools and methods would you want to use to study the human body from that era?

Over the past 2,000 years, the methods used to study anatomy and physiology have evolved significantly, starting from observation and natural remedies in ancient Egypt and China to detailed dissections in ancient Greece. In particular, the work of Hippocrates and Herophilus laid important foundations in understanding diseases and the functions of organs. The Renaissance era marked a turning point when Andreas Vesalius conducted human dissections, allowing for a more accurate understanding of anatomy. The invention of the microscope in the 16th century further advanced the field, enabling scientists to explore previously invisible aspects of human biology. If I could study the human body from any historical period, I would choose the Renaissance and utilize the detailed anatomical sketches created by Leonardo da Vinci, as they beautifully blend artistic observation with scientific inquiry.
