The term cordes vocales, known in English as vocal cords, was coined by French anatomist Antoine Ferrein to describe the laryngeal ligaments. By postulating that these structures functioned similarly to the strings of a violin, he provided a mechanical explanation for the physiology of voice and identified the direct correlation between glottis dimensions and vocal volume.
Early Education and Professional Tenure
Born in 1693 in Frespech, Antoine Ferrein pursued his medical training at the Faculty of Medicine of Montpellier. His career was defined by his roles as a physician, surgeon, and university teacher. His academic work culminated in a long-standing position at the Collège de France, where he taught from 1742 until his death in 1769. During this period, he became a member of the French Academy of Sciences.

Ferrein focused his research on anatomy and anatomical pathology. His observations led to the identification of several structures that now bear his name. These eponyms include Ferrein's canal, which describes the space between closed eyelids and the eyeball facilitating tear flow, and Ferrein's foramen, an opening in the facial canal for the greater petrosal nerve. Additionally, his work on the temporomandibular joint led to the classification of Ferrein's ligament, representing the thickened external portion of the joint capsule.
Renal and Biliary Anatomy
Beyond the larynx and cranial structures, Ferrein documented specific features within the renal and biliary systems. He identified Ferrein's pyramid, also recognized as a medullary ray, which serves as the center of the renal lobule and maintains a pyramid-like structure. His investigations into the liver resulted in the description of Ferrein's vasa aberrantia, which refers to biliary canaliculi that lack connectivity to hepatic lobules.
