Applied Breast And Physiology Of Lactation Flashcards
Explain the role of oxytocin.
Oxytocin - “love hormone” or “cuddle hormone”.
During breastfeeding - oxytocin released in response to baby’s suckling at mother’s breast - causes milk ducts in the breasts to contract, facilitating flow of milk - a process known as let-down reflex.
Oxytocin promotes maternal behavior - increases feelings of relaxation, trust, affection - strengthens emotional bond between mother and baby.
Explain the role of prolactin.
Prolactin - hormone responsible for milk production - prolactin stimulates mammary glands to produce milk when breastfeeding , ensuring adequate milk supply for baby.
Suckling stimulates release of more prolactin, creating a positive feedback loop - maintains milk production.
Explain the role of FIL (Feedback Inhibitor of Lactation).
FIL - a protein produced in mammary glands during lactation - role is to regulate and balance milk production.
FIL acts as an inhibitor of lactation - when breasts are full of milk, FIL is released into the bloodstream - reduces milk production - this mechanism prevents overproduction of milk - allows milk supply to match the baby’s demand.
Explain the role of oxytocin, prolactin and FIL (feedback inhibitor of lactation) with reference to the initiation and maintenance of lactation and mother-infant bonding.
Together, oxytocin, prolactin, and FIL form a complex hormonal system that promotes the initiation and maintenance of lactation.
Oxytocin - triggers the let-down reflex and enhances bond between mother and baby.
Prolactin stimulates milk production.
FIL - provides negative feedback mechanism to regulate milk supply according to the baby’s needs.
Interaction of these hormones facilitates successful breastfeeding, establishment of a strong emotional connections.
