A diagrammatic sectional view of Mammary gland
Mammary gland is a modified sweat gland.
A functional mammary gland is characteristic of all female mammals.
It is a paired structure that contain glandular tissue and variable amount of fat.
Externally each breast is a raised structure and nipples are located in the middle.
- Nipple is covered with light pink or light brown coloured skin having pigments. It is called areola.
The glandular tissue of each breast is divided into $15-20$ mammary lobes containing clusters of cells called alveoli.
- The cells of alveoli secrete milk which is stored in the cavities of alveoli.
- The alveoli open into mammary tubules.
$\Rightarrow$ The tubules of each lobe join to form a mammary duct.
$\Rightarrow$ Several mammary ducts join to form a wider mammary ampulla which is connected to lactiferous through which milk is sucked out.
