Evolution of Anatomical Science and Medical Pioneers

Pioneers of Ancient Anatomy

Alcmaeon was the first to perform a systematic dissection. Although he thought intelligence was in the heart, he eventually helped people understand it was located in the head.

Empedocles believed the heart distributed life-giving heat to the body and held the idea that pneuma flowed through the veins.

Hippocrates, the Father of Medicine, emphasized the importance of the relationship between the patient, the doctor, and the disease, as well as the concept of "crisis" (the point where a patient lives or dies). He utilized the Hippocratic bench, which used tension to aid in setting bones, and established the Hippocratic Oath, which prohibited providing medicine to pregnant women if it could induce an abortion.

Aristotle began dissecting animals and corrected many previous anatomical errors.

Herophilus conducted the first systematic vivisections of criminals and established the brain as the center of intelligence. He performed the first public dissection, mentored the first female medical student, distinguished between veins and arteries, and founded the scientific method.

Erasistratus studied circulation and considered atoms to be essential body elements. He provided the first description of the cerebrum and cerebellum and believed them to be healthy.

The Middle Ages and the Renaissance

Claudius Galenus described many brain structures and recognized the differences between venous (dark) and arterial (bright) blood.

Avenzoar proved that scabies was caused by a parasite, which upset the theory of humorism.

Leonardo da Vinci created detailed drawings of dissections using the cadavers of criminals and discovered the "Divine Proportion" of man.

The Anatomical Theater was the first of its kind, established at the University of Padua.

Andreas Vesalius, the Father of Anatomy, studied in Paris and served as a professor of surgery and anatomy at Padua. In 1540, he demonstrated differences between bodies and published the manuscript De Humani Corporis Fabrica. He studied the bones of the innocent, described the skeletal system as the framework of the body, detailed every muscle location, and used criminal bodies for dissections.

The Scientific Revolution and Modern Anatomy

William Harvey, in 1688, wrote a book in Latin called The Anatomical Function of the Movement of the Heart and the Blood in Animals. He demonstrated that blood does not just drift in the body, correcting the belief that the blood in veins and arteries were different things.

Marcello Malpighi was the first to observe capillaries and noted that the body contains about 100,000 kilometers of them.

Anton von Leeuwenhoek discovered microorganisms and provided descriptions of red blood corpuscles. He made drawings of bacteria (animalculae) and observed spermatozoa in the sperm of dogs.

Henry Gray (1827–1861) was an English anatomist named a Fellow of the Royal Society at the age of 25. In 1825, he published the first edition of Anatomy: Descriptive and Surgical, which consisted of 750 pages and 363 drawings.
