Lactiferous sinus
Lactiferous Sinus
The Lactiferous Sinus (pronunciation: /lækˈtɪfərəs/ /ˈsaɪnəs/) is an important part of the female anatomy specifically related to the mammary gland.
Etymology
The term "Lactiferous Sinus" is derived from the Latin words 'lactifer' meaning 'milk-bearing' and 'sinus' meaning 'pouch' or 'cavity'.
Definition
The Lactiferous Sinus is an expanded segment of the lactiferous duct located in the mammary gland. It serves as a reservoir that holds milk during lactation.
Function
The primary function of the Lactiferous Sinus is to store milk produced in the mammary glands. During lactation, the milk is transported from the alveoli through the lactiferous ducts and into the lactiferous sinuses, where it is stored until it is expressed through the nipple.
