The most important hormone in initiating and maintaining lactation after birth is
(a) estrogen
(b) FSH
(c) prolactin
(d) oxytocin
Guida verificata passo dopo passo1
Understand the role of each hormone listed in the options in relation to lactation and childbirth.
Recall that estrogen primarily prepares the breasts during pregnancy but does not maintain milk production after birth.
Recognize that FSH (Follicle Stimulating Hormone) is mainly involved in reproductive processes like follicle development, not lactation.
Identify prolactin as the hormone responsible for initiating and maintaining milk production in the mammary glands after childbirth.
Note that oxytocin is important for milk ejection (let-down reflex) but does not initiate or maintain milk production itself.
Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Prolactin and its Role in Lactation
Prolactin is a hormone produced by the anterior pituitary gland that primarily stimulates milk production in the mammary glands after childbirth. It initiates and maintains lactation by promoting the synthesis of milk proteins and other components necessary for breastfeeding.

Oxytocin and Milk Ejection Reflex
Oxytocin, released from the posterior pituitary, is responsible for the milk ejection or 'let-down' reflex. It causes the contraction of myoepithelial cells around the alveoli in the breast, enabling milk to be expelled through the ducts, but it does not initiate milk production.

Hormonal Regulation of Lactation
Lactation is regulated by a balance of hormones including estrogen, FSH, prolactin, and oxytocin. Estrogen and FSH primarily regulate reproductive functions, while prolactin initiates milk synthesis and oxytocin controls milk release, highlighting the distinct roles of these hormones in breastfeeding.
