Eponym:

The submandibular duct is eponymously known as Wharton’s duct, named after Thomas Wharton (1614-1673), an English physician and anatomist. Wharton was born in Winterton-on-Tees, County Durham, and earned his medical degree from the University of Oxford in 1647.[3] He later practiced medicine in London and was elected a Fellow of the Royal College of Physicians in 1650.[3] Through meticulous dissection and experimentation, Wharton significantly advanced the anatomical understanding of the salivary glands, particularly the submandibular duct.

Scientific Contributions:

Wharton’s discovery of the submandibular duct was first made during the dissection of a sheep’s head and was subsequently documented in Adenographia (1656).[4] This work became a foundational text in glandular anatomy and was cited extensively by later anatomists and physicians, including Hieronymus Barbatus.[5]  

 

In addition to his work on the salivary glands, Wharton identified the gelatinous connective tissues of the umbilical cord, now known as Wharton’s jelly, which protects umbilical vessels and plays a crucial role in fetal development.[6] Wharton's jelly has since gained research interest for its high concentration of mesenchymal stem cells and potential regenerative uses, showing the enduring relevance of his discovery. Wharton also provided one of the earliest detailed descriptions of the thyroid gland and introduced the term “thyroid,” derived from the Greek thyreous (shield), due to its shape.[2] His systematic and precise approach to anatomical study helped establish foundational principles in glandular physiology and continues to influence modern anatomical science.
