Which of these hormones causes milk ejection from the breasts?

The Role of Hormones in Milk Ejection
In the intricate process of breastfeeding, hormones play a pivotal role, particularly in the ejection of milk from the mammary glands. The hormone primarily responsible for this crucial function is oxytocin.
Understanding Oxytocin’s Function
Oxytocin is often referred to as the “milk ejection hormone.” When a baby suckles at the breast, sensory signals are sent to the mother’s brain, prompting the release of oxytocin from the posterior pituitary gland. This hormone causes the smooth muscles around the milk ducts to contract, effectively pushing the milk toward the nipple, making it available for the infant .
The Lactation Process
The lactation process itself is regulated by a series of hormonal changes that begin during pregnancy. While oxytocin is responsible for milk ejection, prolactin is another key hormone involved in milk production. Prolactin stimulates the mammary glands to produce milk, but it is oxytocin that facilitates its release during breastfeeding.
Conclusion
In summary, while prolactin is essential for the production of milk, it is oxytocin that triggers the ejection of milk from the breasts when a baby suckles. This hormonal interplay is vital for successful breastfeeding, ensuring that infants receive the nourishment they need during their early development.

Which hormone stimulates the production of breast milk Quizlet?

Prolactin is a hormone released from the anterior pituitary gland that stimulates the production of milk.

Which is called milk ejection hormone?

The correct answer for the above question is option ( B ) that is Oxytocin. Note: The hormone oxytocin leads to the milk ejection.

What is the cause of milk coming out from the breast?

Excessive breast stimulation, medicine side effects or conditions of the pituitary gland all may contribute to galactorrhea. Often, galactorrhea results from increased levels of prolactin, the hormone that stimulates milk production. Sometimes, the cause of galactorrhea can’t be determined.

What hormone causes milk ejection from the breast?

When your baby suckles, it stimulates nerves that tell your body to release prolactin and oxytocin. Prolactin causes the alveoli to make milk and oxytocin causes muscle contractions that push out of the alveoli and through the milk ducts.

What is the cause of breast discharge?

Causes of nipple discharge
Common causes include: pregnancy or breastfeeding, which can lead to leaking from your nipples. non-cancerous changes in the breast that happen with age (duct ectasia) a blocked or enlarged milk duct.

What causes the milk ejection reflex quizlet?

Breastfeeding induce a release of the hormone oxytocin which causes contraction of the smooth muscles in the mammary glands and discharge of milk.

What are Montgomery glands?

Montgomery’s glands are large sebaceous glands capable of secreting milk; they represent an intermediate stage between the sweat and the mammary glands. Fascial tissues envelop the breast; the superficial pectoral fascia envelops the breast and is continuous with the superficial abdominal fascia of Camper.

What hormone makes lactate?

Prolactin (also known as lactotropin and PRL) is a hormone that’s responsible for lactation, certain breast tissue development and contributes to hundreds of other bodily processes. Prolactin levels are normally low in people assigned male at birth (AMAB) and non-lactating and non-pregnant people.

What makes breasts lactate?

When your baby suckles, it sends a message to your brain. The brain then signals the hormones, prolactin and oxytocin to be released. Prolactin causes the alveoli to begin making milk. Oxytocin causes muscles around the alveoli to squeeze milk out through the milk ducts.

Which of the following hormones causes ejection of milk?

The posterior pituitary gland secretes oxytocin, which stimulates the myoepithelial cells to contract and eject the milk from the ducts.
