Reference: Berlinghoff, W. P., & Gouva Fernando Q. The remarkable research that took place in Alexandria during the third century BCE was therefore a unique event in the history of medicine and the Ancient World. Erasistratus was also the first to dispel the notion that nerves are hollow and filled with pneuma (air); instead, he averred that they are solid, consisting of spinal marrow.

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. References Adrian Willis in The Lancet quoted Herophilus as having said, "Let the phenomena be described first even if they are not primary.". After studying the flow of blood, he was able to differentiate between arteries and veins. Alexandria was a hub for knowledge and discovery, home to The Royal Library of Alexandria; one of the largest and most significant libraries of the Ancient World, and the Alexandrian Museum, which acted as the worlds chief medical research center. This was especially remarkable because there were no microscopes at the time. This led him to further dissect the eye, and in so doing to discover the cornea, the retina, the iris, and the chorioid coat.

He seems to have employed four main indications of the pulsesize, strength, rate, and rhythm (VIII, 592K.

Diocles wrote the first known anatomy book, Pedanius Dioscorides -- He wrote a five volume book, De Materia, in which he described various herbs and medicinal substances and their properties. He worked out standards for measuring a pulse and could use these standards to aid him in diagnosing sicknesses or diseases. For Herophilus, the ventricles were the seat of both soul and mental functions whereas Galen [27] later favoured the brain substance itself [27].Since the brain was the centre of the nervous system, there must be a passage from it, via the ventricles, into the cerebellum, for the spiritus animalis.Herophilus stressed the importance of the fourth .
