An Introduction to Breast Anatomy
Do you know your breast anatomy? Knowing the parts of the breast, what they do and why they are important is critical knowledge for identifying any abnormalities that might appear in the breast. Read on to learn about your breast anatomy and the function and importance of the parts of your breasts.
Parts of the Breast
Inside the glandular tissues of each of your breasts are the functional parts of the breast, including the following:
Breast Parts and Function
The ducts are the passages that transport the milk from the glands to the nipple. The nipple is located in the center of the colored region known as the areola. This colored area can appear pink to shades of brown.
Once a nursing mother makes milk, it is transported through the ducts to the nipple. As the ducts get closer to the nipple, they get wider to form a sac that is called an ampulla. In your breast anatomy, the spaces between the lobules and the ducts are filled with fat.
Ligaments support and attach your breasts to the front of the chest wall. They attach to both sides of the breastbone or sternum. The breasts are located over the major chest muscle, the pectoralis major.
Vessels in Breast Anatomy
The lymph vessels in your breast anatomy lead from your breasts to the lymph nodes in your body. Clusters of lymph nodes can be found under your arm, above your collarbone, in your chest, and in many other parts of the body.
