Question

1. which answer lists two hormone pathways that involve the hypothalamus and pituitary communicating with one another?○ cortisol and adh○ insulin and glucagon○ androgens and crh○ acth and estrogen

Explanation:

• ADH (antidiuretic hormone) is produced by the hypothalamus and released by the posterior pituitary. Cortisol's pathway involves the hypothalamus secreting CRH, which triggers the pituitary to release ACTH, stimulating cortisol production from the adrenal cortex.
• Insulin and glucagon are produced by the pancreas, with no direct hypothalamus-pituitary communication in their pathways.
• CRH is from the hypothalamus, and androgens are primarily adrenal/gonadal, with no direct pituitary link in this paired pathway.
• Estrogen is gonadal, and ACTH is pituitary-derived, but this pair does not represent two full hypothalamus-pituitary pathways.

Answer:

A. cortisol and ADH
