Question

Explain the structure of mammary glands

Answer 1

BREASTS [MAMMARY GLANDS] :-

These are a pair of rounded structures found in pectoral region on ventral thoracic wall. Each has an erectile nipple in the middle. These are modified sweat glands. Each breast contains fatty connective tissue and numerous lactiferous glands.
The glandular tissue of each breast divided into 15 to 20 mammary lobes containing clusters of cells called alveoli. The cells of alveoli secrete milk which is stored in the cavities (lumens) of alveoli. The alveoli open into mammary tubules. The tubules of each lobe join to form a mammary duct. Several mammary ducts join to form a wider mammary ampulla just beneath the nipple to store the milk. The ampulla is connected to the lactiferous duct through which milk is sucked out via the nipples. The base of the nipple shows dark brown rounded area called
Areola.
Release of milk from breast is under the control of Prolactin and Oxytocin hormones.
