Step-by-step solution
Pituitary gland or hypophysis is situated in a depression, the sella turcica of sphenoid bone of the skull. It is directly attached to the hypothalamus by a stalk, the infundibulum. Hypophysial portal veins carry blood containing neurohormones (releasing factors) from the hypothalamus to the anterior pituitary.
