Hypothalamic pituitary dysfunction etiologies

Which of the following statements correctly describes a similarity between the anterior pituitary and posterior pituitary?

1: Hypothalamus-derived hormones (releasing hormones) trigger the release of hormones from both the anterior pituitary and posterior pituitary.
2: The anterior pituitary and posterior pituitary are both connected to the hypothalamus via the hypophyseal portal system.
3: The anterior pituitary and posterior pituitary both release hormones synthesized in the hypothalamus.
4: The anterior pituitary and posterior pituitary both respond to input from the hypothalamus, which coordinates the hypothalamic-pituitary-endocrine axes.
