The duct of Wharton is a term used in anatomy to describe a specific structure in the human body. It refers to the main excretory duct of the submandibular salivary gland, also known as the submandibular duct. This duct is named after the English anatomist Thomas Wharton, who first described it in the 17th century.
The duct of Wharton starts at the sublingual gland, a salivary gland located underneath the tongue, and travels in a downward and forward direction before entering the floor of the mouth. It then opens into the oral cavity through a small hole called the sublingual papilla, located on the sublingual caruncle, a small raised area on the floor of the mouth.
The primary function of the duct of Wharton is to transport saliva produced by the submandibular gland to the oral cavity. Saliva, a watery fluid containing enzymes and lubricants, plays a crucial role in digestion by moistening food, aiding in swallowing and breaking down carbohydrates.
Any blockage or inflammation within the duct of Wharton can hinder the normal flow of saliva, leading to conditions like sialolithiasis or salivary gland infections. These conditions can cause pain, swelling, and difficulty in eating and speaking. Medical interventions such as salivary gland massage, warm compress, or surgical procedures may be required to address these issues.
In summary, the duct of Wharton, or the submandibular duct, is the main excretory channel responsible for carrying saliva from the submandibular gland to the oral cavity for digestion and oral hygiene.
