Before - record keeping Having drawn the distinction between veins and arteries, Praxagoras gave the pulse a role in diagnosis and therapeutics. 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 believed this was the seat of the human soul or psyche. Alcmaeon of Croton distinguished veins from arteries. 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 Herophilus remarkable work effectively superseded that of his predecessors; later medical writers such as Roman doctor Galen of Pergamon adopted his interpretation over Aristotles.

Philosophy and History of Asian Medicine. In Alexandria he lived in an environment in which the dissection of the human body did not meet with general disapproval.1 Such an atmosphere, possibly unique in Greek cities at that time, clearly proved beneficial to the development of scientific anatomy, and Herophilus researches significantly advanced this study. ." Neurosurg Focus. He also wrote on obstetrics and gynecology and held an elaborate quantitative theory of the pulse. He was among the first to introduce the notion of conventional terminology, as opposed to use of "natural names", using terms he created to describe the objects of study, naming them for the first time. Rachel HajarM.D. In this instance he did not use the technical term but retained the more familiar terminology. To make this consistent with medical beliefs at the time, Herophilos stated that diseases occurred when an excess of one of the four humors impeded the pneuma from reaching the brain. Thus, although Praxagoras did not himself actually isolate and identify the nerves as such, he nevertheless played an important role in their discovery a generation later by Herophilus. He devised a water clock to measure the pulse. 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. 280 BC - Herophilus Dissection studies the nervous system and distinguishes between sensory nerves and motor nerves and the brain. ; I.

Adrian Willis in The Lancet quoted Herophilus as having said, "Let the phenomena be described first even if they are not primary.". It was his work on the nervous system, however, that was considered to have been the most important. . - health care silos He recorded his findings in over nine works, which are now all lost. Among their neuroscientific achievements were the discovery of the cranial nerves, the meninges, the dural sinuses and the ventricles; the delineation of the motor and sensory nerves; the appraisal of the brain as the seat of consciousness and human intellect; and the attribution of neurological disease to dysfunction of the nervous system. Having thereby provided specific channels through which voluntary motion could be imparted to the body, Praxagoras then conjectured that certain arteries became progressively thinner, with the result that ultimately their walls fell together and their hollowness () disappeared.

Through his dissection of the eye, he discovered its different sections and layers: the "skin" of the eyeball comprising the cornea (the clear part at the front of the eye through which light begins to be focussed into the eye) and sclera (the white of the eye), the iris (the colored part of the eye surrounding the pupil), the retina (containing the cells converting light into neural activity), and the choroid (a layer between the retina and the sclera comprising connective tissue and blood vessels nourishing the retina).
