2. **Prolactin**: Produced by the anterior pituitary. It primarily stimulates the mammary gland alveolar cells to **synthesize and produce milk**.
3. **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.
4. **Mnemonic**: Prolactin = Production; Oxytocin = Out (ejection).
