In reality, milk comes from many openings in the nipple. Called milk duct orifices, these tiny holes usually number from around four to twenty per breast.
The outer breast consists of a nipple and areola. The tip of the nipple contains several hole openings allowing for milk to flow through during lactation. The areola is the pigmented area around the nipple. It is covered with Montgomery glands that secrete oil to lubricate the nipple and areola.
Montgomery glands
The darker area of skin around the nipple is called the areola. On the areola there are some little raised bumps. These are quite normal and are called Montgomery glands. They produce fluid to moisturise the nipple.
The milk ducts, also called lactiferous ducts, are the tubes that carry your breast milk from where it is made in the glandular tissue of your breast out to your nipple. There are approximately 15 to 20 milk ducts located in your breast.
Nipple pores are the openings of the nipple ducts that lead to the milk chambers in the breast where the female body stores breast milk. When someone is breast-feeding, nipple pores and ducts can sometimes get blocked with milk. Symptoms and treatments vary, depending on the length of time they remain blocked.
Nipples just do not have a single opening. Milk comes out through multiple tiny holes called the milk duct orifices or nipple pores. These milk duct orifices have their own sphincters to keep the milk from leaking. Some of these duct orifices are located at the center and a few outsides of it.
Most pimples on the nipple should be left alone. The body will clear them without outside help, and popping them can make them worse. This is especially true on sensitive skin areas, including the nipple.

How do I know whether my breasts are empty? There's no test or way to know for sure. In general, though, if you gently shake your breasts and they feel mostly soft and you don't feel the heaviness of milk sitting in them, you're probably fine.
Despite views to the contrary, breasts are never truly empty. Milk is actually produced nonstop—before, during, and after feedings—so there's no need to wait between feedings for your breasts to refill. In fact, a long gap between feedings actually signals your breasts to make less, not more, milk.
Montgomery tubercles, also known as Montgomery glands, are raised white bumps that look similar to goosebumps on the nipple and surrounding areola. They are named after William Fetherstone Montgomery, an Irish physician and obstetrician who first described them in 1837.
Estrogen controls the growth of the ducts, which is why the areolas and nipples tend to get firmer and the ducts more prominent during the middle stages of the menstrual cycle (when estrogen levels are at their highest).
The crustiness you're referring to is likely related to the discharge from the nipple that has dried, forming a crusty scale. In most cases, nipple discharge is nothing to worry about. It could be due to cysts in the breasts, non-cancerous tumors, or infection, among other conditions.
If you're breast-feeding, ducts carry milk from the alveoli toward the dark area of skin in the center of the breast (areola). From the areola, the ducts join together into larger ducts ending at the nipple.
Some women notice that they become aroused during breastfeeding. Although this sensation is similar to a sexual response, it is not sexually driven. It is your body's way of preparing the breast for breastfeeding.
Galactorrhea is a condition where your breasts leak milk. The main sign of galactorrhea is when it happens in people who aren't pregnant or breastfeeding. It's caused by stimulation, medication or a pituitary gland disorder.
Your breasts feel softer
This happens as your milk supply adjusts to your baby's needs. The initial breast fullness reduces in the first few weeks. At around 6 weeks, breast fullness is completely gone and your breasts may feel soft. This is completely normal and has no effect on your milk supply.
Some women feel the let-down reflex as a tingling sensation in the breasts or a feeling of fullness, although others don't feel anything in the breast. Most women notice a change in their baby's sucking pattern as the milk begins to flow, from small, shallow sucks to stronger, slower sucks.
As females get older, their bodies start to produce less of the reproductive hormone estrogen than before. Estrogen stimulates the growth of breast tissue, while low levels of this hormone cause the mammary glands to shrink.
We found that the skin of the superior quadrant was the most sensitive part of the breast, the areola was less sensitive, and the nipple was the least sensitive part.
There are several causes of nipple or areola dermatitis. These include eczema and irritation or allergic dermatitis. Certain types of dermatitis can also cause eczema. Eczema is a common condition in breast-feeding women, especially those who have previously been affected by atopic dermatitis.
Galactorrhoea is milky nipple discharge not related to pregnancy or breast feeding. It is caused by the abnormal production of a hormone called prolactin. This can be caused by diseases of glands elsewhere in the body which control hormone secretion, such as the pituitary and thyroid glands.
About 20% of breastfeeding mothers report seeing fluid coming from their Montgomery glands. This happens because these important glands consist of both milk glands and sebaceous (sweat) glands. Breast milk travels down the breast ducts to the nipples, where it's available for a baby to drink.
As you reach the age of 40 years and approach perimenopause, hormonal changes will cause changes to your breasts. Besides noting changes in your breasts' size, shape, and elasticity, you might also notice more bumps and lumps. Aging comes with an increased risk of breast cancer.
