Epidemiological Timeline by Haley Rust | Timetoast timelines Herophilus also succeeded in tracing the sensory nerves leading from the brain to the eyes (III, 813K.) Herophilus based this assertion upon comparative thickness and estimated that the walls of an artery were six times as thick as those of a vein (see also II, 624K.).

An excess of yellow bile led to violence, vengeance, shorttemperedness, and ambition. 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.

Galen tells us that it was by the operation of these that Praxagoras accounted for the movement of the fingers and other parts of the hands. To measure this pulse, he made use of a water clock. Herophilus demonstrated the meninges, and ventricles, regarding the fourth as most important. 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. He also catalogued and described many of the nerves located in the cranium, including the optic nerve for sight and the oculomotor nerve for eye movement, as well as facial, auditory, and hypoglossal (tongue) nerves. Other areas of his anatomical study include the liver, the pancreas, and the alimentary tract, as well as the salivary glands and genitalia. He believed this was the seat of the human soul or psyche. Herophilos's work on blood and its movements led him to study and analyse the brain. doi: 10.3171/foc.2007.23.1.12. Hornblower, S.& Spawford, A.
