Charles Marie Benjamin Rouget

From Wikipedia, the free encyclopedia

Charles Marie Benjamin Rouget (August 19, 1824 - 1904) was a French physiologist who was born in Gisors. He studied at the Collège Sainte-Barbe with medical training at hospitals in Paris. He was later a professor of physiology at the University of Montpellier.

Rouget is mostly remembered for his correlation of physiology to microscopic anatomical structure. He was the first to discover the branching contractile cells on the external wall of the capillaries in amphibians, which are now known as Rouget's cells. Also the eponymous Rouget's muscle was described by him, which are circular fibers of the ciliary muscle of the eye. These fibers are often called Horner's muscle because of its association with Horner's syndrome.
