Ductuli transversi

Ductuli transversi are a part of the mammary gland system in mammals. They are small ducts that transport milk from the lobules, where it is produced, to the larger lactiferous ducts, which carry the milk to the nipple. The term "ductuli transversi" is derived from Latin, with "ductuli" meaning "small ducts" and "transversi" meaning "crossing over" or "transverse".

Anatomy

The mammary gland is a complex network of ducts and lobules. The ductuli transversi are located within the lobules and serve as a bridge between the lobules and the larger lactiferous ducts. They are lined with epithelial cells, which are responsible for the production and secretion of milk during lactation.

Function

The primary function of the ductuli transversi is to transport milk from the lobules to the lactiferous ducts. During lactation, the epithelial cells lining the ductuli transversi produce and secrete milk. This milk is then transported through the ductuli transversi to the lactiferous ducts, which carry it to the nipple where it can be accessed by a nursing infant.

Clinical significance

Abnormalities in the ductuli transversi can lead to a variety of medical conditions. For example, blockages in these ducts can cause mastitis, a painful infection of the mammary gland. Additionally, changes in the cells lining the ductuli transversi can lead to the development of breast cancer.
