Accessory gland
Accessory Gland
The Accessory Gland (pronounced: əkˈses(ə)rē gland) is a term used in the field of Anatomy and Physiology to describe any gland that supplements the function of the primary glands in the body.
Etymology
The term "Accessory Gland" is derived from the Latin word "accessorius" meaning additional, and the Greek word "adēn" meaning gland.
Function
Accessory glands are typically associated with the Digestive System, Reproductive System, and Respiratory System. They produce and secrete substances that aid in the functioning of the primary glands. For example, in the digestive system, the Salivary Glands, Liver, and Pancreas are considered accessory glands as they produce enzymes and other substances that aid in digestion.
In the reproductive system, accessory glands such as the Prostate Gland, Seminal Vesicles, and Bulbourethral Glands in males, and Bartholin's Glands and Skene's Glands in females, produce fluids that nourish and protect the sperm and egg cells, and facilitate their transportation.
In the respiratory system, accessory glands like the Lacrimal Glands and Mucous Glands produce tears and mucus respectively, which help to moisten and protect the respiratory tract.
