Who Was Jean Fernel?

Jean François Fernel (Latinized as Ioannes Fernelius; 1497 – 26 April 1558) was a French physician who introduced the term "physiology" to describe the study of the body's function. He was the first person to describe the spinal canal. The lunar crater Fernelius is named after him.

Fernel suggested that taste buds are sensitive to fat, an idea which research in the early 21st century proved to be correct.
