Erasistratus of Chios (330? BC - 250? BC) was a Greek anatomist. He worked as royal physician under Seleucus I Nicator and founded a school of anatomy in Alexandria along with Herophilos. He regarded atoms as the essential body elements, and they were vitalized by external air (pneuma) circulating through the nerves. He also thought that the nerves moved a "nervous spirit" from the brain, from which Erasistratus traced sensory and motor nerves. He also believed that the arteries moved an "animal spirit" from the heart by air provided by the lungs. He is best known for curing Antiochos, Seleucus's son. Erasistratus said that Antiochos was in love with his stepmother, and that that was what was ailing him, so he let them marry.

Erasistratus of Chios, Greek Physician born in Chios.
Erasistratus lived from 310 BC until 250 BC and is considered to have founded the school of Alexandria.
Erasistratus was the house physician of Seleucas, the king of Syria, and was called when his oldest son Antiochus was ill. Erasistratus examined him but did not find anything.
Erasistratus, considered the father of physiology, was born on the island of Chios in ancient Greece.
Erasistratus accurately described the structure of the brain, including the cavities and membranes, and made a distinction between its cerebrum and cerebellum (larger and smaller parts).
Erasistratus understood that the heart served as a pump, thereby dilating the arteries, and he found and explained the functioning of the heart valves.
