Question

Draw the hypothalamic-hypophyseal pathways that regulate the release of thyroid hormone, cortisol, testosterone, prolactin, and growth hormone. For each pathway (you should have 5) begin with the hypothalamus, end with the final gland in the pathway, label each of the glands, and list the hormone each gland releases.

Answer 1

Hypothalamus--> Thyroid releasing hormone (TRH)--> Adeno-Hypopyhesis-->Thyroid Stimulating Hormone--> Thyroid-->T3 and T4 are produced by the gland

Hypothalamus--> Corticotropin releasing hormone --> Adeno-Hypopyhesis-->Adenocorticotropic Hormone--> adrenal cortex-->cortisol is produced by the gland

Hypothalamus--> Gondotropic releasing hormone --> Adeno-Hypopyhesis-->Follicle stimulating or Luteinizing Hormone--> Testes --> Testesteron

Hypothalamus--> Prolactin releasing hormone --> Adeno-Hypopyhesis--> ProlactinHormone--> mammary gland --> milk production

Hypothalamus--> Growth hormone releasing hormone --> Adeno-Hypopyhesis--> Growth Hormone--> Liver + Body-->
