1,2,3,5
Rationale 1: The anterior pituitary produces adrenocorticotropic hormone.
Rationale 2: The anterior pituitary produces thyroid-stimulating hormone.
Rationale 3: Gonadotropin-releasing hormone is released by the hypothalamus and stimulates the anterior pituitary to secrete the gonadotropic hormones, follicle-stimulating hormone and luteinizing hormone. If the anterior pituitary is damaged, this secretion cannot occur.
Rationale 4: Antidiuretic hormone is secreted by the posterior pituitary.
Rationale 5: Somatostatin inhibits growth hormone and thyroid-stimulating hormone release from the anterior pituitary. If the anterior pituitary is damaged, this release cannot take place.
