Pituitary structure
        Divided into anterior (adenohypophysis) and posterior (neurohypophysis).
        Controlled by hypothalamic releasing/inhibiting hormones via 

                    pituitary portal system (anterior) or 

                    direct neural connections (posterior).

Anterior pituitary hormones
FLAT PEG:
  – FSH, LH → gonads
  – ACTH → adrenal cortex
  – TSH → thyroid
  – Prolactin → breast
  – GH → liver & tissues
  – (Endorphins)
Disorders often affect multiple axes.

Posterior pituitary hormones
ADH (vasopressin) and oxytocin synthesised in hypothalamus, released from posterior pituitary.
