Mammary Gland : The structure of the mammary gland


 What is Mammary Gland?

The mammary gland is an important organ of the female reproductive system. It is responsible for the production of milk for the nourishment of the young. The mammary gland is composed of a network of ducts and lobules that empty into the nipple. The ducts and lobules are lined with epithelial cells that secrete milk.

Mammary gland is an accessory reproductive gland in female mammals that produces milk for nursing their young. In all mammals, the mammary glands are enlarged and well developed only during pregnancy and lactation. In humans, these glands are generally found only in women, although lactation occasionally occurs in men and women who have been treated with certain hormones. The milk produced by the mammary gland provides nutrients and immunity to the young.

The structure of the mammary gland

The structure of the mammary gland is unique in several ways. The primary way in which it is unique is the way in which it is composed of several distinct regions, each with a specific purpose. The gland is also unique in the way that it is able to produce milk, and in the way that it is able to store milk for periods of time.

The shape of the mammary gland may be labeled into 3 sections – skin, stroma and parenchyma.


The skin comprises the areola and the nipple.


  • It is the pinkish-brown, darkish pigmented area around the nipple

  • These are rich in altered sebaceous glands which produce oily secretion preventing cracking of the areola and the nipple

  • This region does no longer have hair and fats


  • This is a conical eminence located in the 4th intercostal space

  • Around 15-20 lactiferous ducts penetrate the nipple

  • It accommodates longitudinal and round easy muscle fibers. They are richly furnished with nerves

  • Smooth muscle mass assists in erecting nipples on being inspired. The nipples are without any fat, sweat glands and hair on them


It bureaucracy the supportive framework of the breast surrounding the parenchyma.

  • Fatty stroma – Despite the fact that the areola and nipple lack fats, the primary bulk of the mammary gland is packed with differing portions of fat

  • Fibrous stroma – It produces the septa known as the suspensory ligaments of Cooper accountable for isolating lobes and suspending the mammary glands from the pectoral fascia. Along with the cutaneous edema, the shortening of the ligaments produces a trendy look reminiscent of an orange peel, so known as the Peau d’ orange appearance.

What is the role of the mammary gland?

The mammary gland is an important organ in the body which is responsible for producing milk for nursing infants. The gland is also responsible for secreting other substances such as enzymes and hormones. The mammary gland is composed of two main types of cells: epithelial cells and stromal cells. Epithelial cells are the cells that line the inside of the gland and are responsible for producing milk.

The mammary gland is an organ in female mammals that produces milk for nursing their young. It is typically located in the breast. The mammary gland consists of 15 to 25 lobes, each of which has its own lactiferous duct that drains into a nipple. The milk produced by the mammary gland contains antibodies that help protect the infant from infection.

How does the mammary gland work?

  • The mammary gland is an organ that produces milk for nursing infants. It is composed of two lobes, each of which is drained by a lactiferous duct that opens at the nipple. The glandular tissue of the lobes is arranged in 15 to 20 concentric circles of alveoli, the smallest of which are at the periphery of the gland. The alveoli are lined with milk-secreting epithelial cells and are surrounded by myoepithelial cells, which contract to expel milk from the alveoli.

  • The glandular tissue of the mammary glands are composed of branching ducts and the terminal secretory lobules. About 15-20 lobes and a lactiferous duct drain every one of them. Such ducts enlarge, forming the lactiferous sinus earlier than it one by one opens into nipples. Milk is assembled inside the lactiferous sinuses and out as soon as the toddler suckles. The lactiferous ducts are radially organized inside the nipples.

  • Until puberty, there may be minimum breast improvement and may be compared in both sexes. At the time of puberty, within the effect of flowing growth hormones and estrogen, there may be a speedy development of breasts in females with widespread development of the adipose tissue. This is how breasts get a clean contour. Same manner, at the time of early pregnancy, there is a rapid boom in the length of breasts due to better increase of parenchyma and branching within the ductal device.

  • Such modifications are an end result of a surge within the progesterone and estrogen hormones. The secretory alveoli begin to broaden at the duct terminals and are wrapped by means of the connective tissue. In the similar stages of pregnancy, such alveoli are loaded with milk underneath the motion of prolactin. After the termination of lactation, the secretory alveoli start to decrease and decrease in size and number and disappear eventually. However, the mammary glands do no longer go back to the pre-pubertal segment. In the later levels of existence, especially put up-menopause, breasts exhibit intense regression of their length.

What affects the health of the mammary gland

The mammary gland is often referred to as a milk-producing gland and is found in all mammals. The health of the mammary gland is essential to the health of the animal. There are many factors that can affect the health of the mammary gland. Some of these factors include: nutrition, genetics, environment, and disease.

Various factors affect the health of the mammary gland. First, there is the composition of the milk. Second, there is the quality of the milk. Third, there are the physical and chemical characteristics of the milk.
