ANATOMI PAYUDARA DAN FISIOLOGI LAKTASI/MENYUSUI

Summary

In this educational video, Dina Sari presents an in-depth explanation of breast anatomy and the physiology of lactation. She outlines the development and structure of the female breast, detailing its components such as the areola, nipple, Montgomery glands, and adipose tissue. Dina also covers how hormonal changes influence lactation, emphasizing the roles of prolactin and oxytocin in milk production and release. Additionally, she discusses key reflexes involved in breastfeeding, including the let-down reflex and the baby's sucking mechanism, offering a comprehensive understanding of the biological processes behind breastfeeding.

Takeaways

• 😀 The anatomy of the breast includes various parts like the skin, areola, nipple, Montgomery glands, adipose tissue, and lobes, each with distinct functions in lactation and sexual activity.
• 😀 Breasts in women develop during puberty and vary in size, shape, and positioning, but these differences are considered normal.
• 😀 The areola, which is darker than the surrounding skin, may change color during pregnancy and breastfeeding to aid in breastfeeding.
• 😀 The nipple has several ducts that allow milk to be expressed during breastfeeding, while Montgomery glands secrete natural oils to lubricate and protect the skin.
• 😀 Adipose tissue, or fatty tissue, plays a significant role in determining breast size and composition, varying between women.
• 😀 The lobes of the breast contain milk-producing cells (alveoli), which are connected to milk ducts that transport the milk to the nipple.
• 😀 There are ligaments that connect the breast tissue to the chest wall, helping to support the shape and position of the breast.
• 😀 The hormonal regulation of lactation is controlled by estrogen, progesterone, and prolactin, which affect milk production and release.
• 😀 During lactation, there are two key reflexes: the prolactin reflex (stimulating milk production) and the let-down reflex (stimulating milk ejection).
• 😀 The sucking reflex of the baby stimulates nerve impulses in the breast, signaling the brain to release prolactin and oxytocin, promoting milk production and flow.
• 😀 Successful breastfeeding depends on the baby's ability to latch and suck effectively, with reflexes such as rooting, sucking, and swallowing facilitating milk intake.

Q & A

What changes occur in the breast during puberty in women?

During puberty, the breasts in women enlarge and begin to protrude, with significant development of the breast tissue. This growth is driven by hormonal changes, primarily estrogen.

What is the primary function of the female breast?

The primary function of the female breast is to produce breast milk (ASI or Air Susu Ibu) to nourish infants. It also serves as a sexual organ.

How does the size and shape of breasts vary among women?

Breast size and shape can vary greatly between women. These differences are often due to the amount of fatty tissue in the breast, and one breast may also be slightly larger or higher than the other, which is normal.

What are the main components of the anatomy of the breast?

The breast consists of several components: skin, areola (the darker area around the nipple), nipple (the protruding part that releases milk), Montgomery glands (which secrete natural oils), fatty tissue (adipose tissue), lobes (which produce milk), ducts (which transport milk), and ligaments that support the breast.

What is the role of Montgomery glands in the breast?

Montgomery glands, found around the areola, produce a natural oil that helps to lubricate and protect the skin of the breast, especially during breastfeeding.

How does the process of lactation work in terms of hormone regulation?

During lactation, two key hormones are involved: prolactin, which stimulates milk production, and oxytocin, which stimulates the release of milk. These hormones are influenced by the baby's suckling, which triggers a reflex response in the mother.

What is the 'let-down reflex' in lactation?

The let-down reflex, also known as the milk ejection reflex, occurs when oxytocin is released from the posterior pituitary gland, causing the muscles around the mammary glands to contract and release milk into the ducts.

What happens during the 'prolactin reflex'?

The prolactin reflex is triggered by the baby's suckling, sending nerve impulses to the brain, which stimulates the anterior pituitary gland to release prolactin. This hormone stimulates the production of milk in the alveoli of the breast.

What are the different types of nipple shapes and what do they signify?

Nipples can have various shapes, such as normal, short, inverted, or flat. Inverted or flat nipples do not necessarily indicate any issue, and women with these types can still breastfeed successfully.

What is the effect of breastfeeding on a woman's fertility?

Exclusive breastfeeding can delay the return of fertility by suppressing ovarian function due to the high levels of prolactin. This can reduce the likelihood of conception during the breastfeeding period.
