Estrogen progesterone prolactin and oxytocin.

Anatomy when breastfeeding. The ductal system is largely dormant until pregnancy. Tubes called ducts carry the milk from the alveoli towards the nipple. Breast development begins in puberty and cyclical hormonal changes promote development and proliferation of adipose tissue and the ductal system which will ultimately be required for lactation.

In order to understand breastfeeding and to maximize your milk supply it is helpful to understand the structures of the breast and the process of how milk is made. They have no role in making milk. Male and female breast nipples have many nerves that enhance sexual arousal.

Milk is secreted from the lactocytes fills the alveoli and is squeezed into the ducts. This chapter will review the anatomy and physiology of breastfeeding. Other areas that require attention are the behavior correlates of breastfeeding and the transfer of drugs and toxins into milk.

All genders can get breast cancer. Maternal hormonal effects and regulation determine milk supply in a time dependent manner. Female breasts have milk ducts and glandular tissue that aid breastfeeding.

Each breast has around 20 large milk ducts delivering milk to areola. Previous descriptions derived from direct scientific observations are impressive for their simplicity and logic but they have not received. Milk composition varies through time in its nutritional and cellular components.

These findings have provided insight in to breast function and the breastfeeding process and will ultimately allow for imp-roved support of the breastfeeding mother. Ex-smokers were more likely to intend to breastfeed p. Women are more prone to benign noncancerous breast disease.

The Anatomy of the Breast This diagram shows the internal structure of the breast. Knowledge of the anatomy of the breast. The nipple of the post-partum female is used by the infant to breastfeed.

Areola is the dark skin around nipples this is where the baby has to suck to get milk. Alveoli are the glandular tissue where milk is produced. Understanding breast anatomy and lactation physiology will allow physicians to gain knowledge of the processes which control lactation enabling physicians to appropriately manage the breastfeeding dyad.

Breastfeeding is a complex biological process involving a delicate balance of four hormones namely. The description of the dynamic anatomy of normal sucking is drawn both from older and from more recent studies of infants feeding at the breast. There are key anatomic factors to consider in the infant and breast anatomy regarding breastfeeding.

Breast alveoli are balloon-like structures lined with milk-secreting cuboidal cells or lactocytes that are surrounded by a net of contractile myoepithelial cells. Anatomy of the lactating breast When performing ultrasound scans on the lactating breast Dr Donna Geddes from The University of Western Australia began to question the anatomical diagrams that appeared in textbooks. The body will be able to do the necessary adjustments in the level of these hormones in order to make store and eject breast milk.

There are many books that describe breast anatomy and changes during pregnancy and lactation for those who would like to delve more fully into. 1 New York NY USA 21 Anatomy This overview is not meant to be comprehensive. The standard model of the breast was based on anatomical dissections carried out on cadavers by Sir Astley Cooper in 1840.

The breasts are paired structures that lie in front of the anterior thoracic wall over the pectoralis major muscle. When a human babychild breastfeeds or a breastfeeding woman expresses and the let-down reflex is triggered the milk flows out of the nipple via tiny openings called duct openings. The breast has typically about 15 to 20 of these structures.

Hormones of pregnancy trigger crucial changes in the breasts. The small darkened pigmented area around the nipple is called the areola. The interplay of hormones involved in lactation and milk management affect milk initiation as well as ongoing milk production galactopoesis.

Fat and muscles fills most of the breast they give size and shape to breast. During the first half of pregnancy there is intense lobular-alveolar. The size of the breast is not related to how well it can make milk.

Rather it contains key factors that help provide a context in which to discuss breastfeeding. The general understanding of the mechanisms of milk secretion is fairly good but the regulatory mechanisms at the cellular and molecular levels have not been given adequate attention and are ripe for future investigation. Anatomy and pregnancy Two stages of breast growth occur during pregnancy.

Cross Section of a Lactating Breast Breast milk travels from the cluster of alveoli the alveolus also called milk-producing cells glandular tissue mammary glands or milk glands then into the milk ducts and then out of the nipple openings. The breast anatomy of males and females is slightly different. The nipple becomes erect because of such stimuli as a cold environment breastfeeding and sexual activity.
