An official website of the United States government. The three membranes of the brain were also recognized by Herophilus and designated as chorioid () because they resembled the chorionic envelope surrounding the fetus (II, 719K.).

It has been theorized that accusations of vivisections is the main reason why Herophilus has not received as much recognition for his scientific investigations of the human body as Hippocrates, Galen, or Vesalius. His method proved to be a potent research tool, affording him unparalleled advantages over previous students of human anatomy who had formulated their insights mainly on indirect evidence and speculation. Despite their significant contributions, their legacy is shrouded with great controversy and grave accusations; they were accused of the unspeakable: performing vivisections on live humans. 27 Apr. 280 BC Herophilus studies the nervous system 130 BC Birth of Galen.

Later physicians, such as Cornelius Celsus and Galen charged both Herophilus and Erasistratus with performing vivisection on condemned criminals awarded to them by the rulers of Alexandria.

(April 27, 2023). He made remarkable progress in anatomy, complementing Herophilus teachings and research, and describing the brain even more accurately, distinguishing the cerebrum from the cerebellum and sensory from motor nerves. Herophilus maintained that pulsation was entirely involuntary and was caused by the contraction and dilatation of the arteries in accordance with the impulse received from the heart (VIII, 702K.). 460 BC Birth of Hippocrates, the Greek father of medicine begins the scientific study of medicine and prescribes a form of aspirin. At the time, Alexandria was the center of learning and scholarship, and learned men from througthout the known world visited its famous library. Herophilus recorded his findings in over nine works that were kept at the library in Alexandria for almost 700 years until a massive fire destroyed all of his writings in 391 CE. Dissecting with the purpose to gain knowledge about human anatomy started again in early modern times (Vesalius), more than 1600 years after Herophilos's death.

Herophilus discovery, by dissection, of the nerves and his demonstration that they originate in the brain enabled him to answer the question raised by Praxagoras: to what kind of organ the extremities of the body owe their movement. Last revised: He took deep interest in general anatomy, and soon realized that the only way he could truly study human anatomy was by becoming the first person to perform systematic dissection of the human body, presumably on cadavers. He noticed that the arteries pulsed and he worked out standards for measuring this pulse and using it in diagnosis. References Tertullian, writing in the next century, called Herophilus a butcher, implying that he cut up living people. In The Oxford Classical Dictionary. Disclaimer. Epub 2018 Aug 31. He was a forerunner of the Empiric school of medicine, founded by Herophilos's pupil Philinus of Cos,[5] which combined Herophilos's empirical impulses with critical tools borrowed from Pyrrhonist philosophy.

FOIA 460 BC Birth of Hippocrates, the Greek father of medicine begins the scientific study of medicine and prescribes a form of aspirin. As a member of the well-known scholastic community in the newly founded city of Alexandria during the single, brief period in Greek medical history when the ban on human dissection was lifted, Herophilus studied the ventricles (cavities) of the brain, the organ he regarded as the centre of the nervous system; traced the sinuses of the dura mater (the tough membrane covering the brain) to their junction, known as the torcular Herophili; and classified the nerve trunksdistinguishing them from tendons and blood vesselsas motor or sensory.
