| Herophilus | <person> Herophilus of Chalcedon is the early "Father of Anatomy" and Galen remarked that he was the first to have dissected human and animal bodies. Pliny states Herophilus was the first man to search for the cause of disease by human dissection, and goes on to say that Pharaoh Ptolemy witnessed some of these dissections. Celsus gave Herophilus credit for using prisoners condemned to die as subjects of study immediately previous to their last breath, by order of the sovereign. He was the first to accurately differentiate nerves, tendons, and arteries from veins. He divided motor from sensory nerves. He taught that the brain was the seat of the intelligence. He recognised pulsations in arteries and counted them with the aid of a clepshydra or water-clock. Herophilus gave us the name of the first part of the small intestine, the duodenum, which means "12 fingers long." He also named the prostate gland which means "guard" of the bladder. His name is attached to the confluence of the venous sinuses in the occipital region of the cerebrum (the torcular of Herophili). This keen anatomist described the liver, pancreas, salivary glands, chyliferous vessels, and genital organs from which he wrote at least nine treatises. Is there any wonder that he is referred to as the early Father of Anatomy ! Lived: 300-344 B.C. (15 Nov 1997) |

| Herophilus |
Herophilos, sometimes Latinized Herophilus (335-280 BC), was a Greek physician. He was born in Chalcedon in Asia Minor (now Kadik?, Turkey). He is known as the first anatomist in history. Together with Erasistratus he is regarded as a founder of the great medical school of Alexandria. He was the first to base his conclusions on dissection of the human body. He studied the brain, recognizing it as the center of the nervous system and the site of intelligence. ...

| Herophilus of Chalcedon |
a Greek physician at Alexandria, c. 300 B.C., a pupil of Praxagoras and an elder contemporary of Erasistratus. He performed public human post mortems and possibly also vivisection on condemned criminals. In his studies of the brain (for him the seat of intelligence and the organ of the soul) he distinguished the cerebrum from the cerebellum, described and named the meninges, calamus scriptorius, and the torcular Herophili. He studied the vascular and nervous systems and distinguished sensory from motor nerves, tendons from nerves, and veins from arteries. Herophilus recognized that the pulse derives from the heart and is not an innate function of the arteries; he classified pulses by speed, regularity, and other factors; and he furnished a mathematical law of systole and diastole.
