Select the correct option:
Solution
Incorrect! Answer:
Milk synthesis
- Lactation Hormones: Two main pituitary hormones control breastfeeding.
- Prolactin: Produced by the anterior pituitary. It primarily stimulates the mammary gland alveolar cells to synthesize and produce milk.
- Oxytocin: Produced by the hypothalamus (released by posterior pituitary). It triggers the contraction of myoepithelial cells, leading to milk ejection (the 'let-down' reflex) in response to suckling.
- Mnemonic: Prolactin = Production; Oxytocin = Out (ejection).
